Gundlach's WoW Stuff
These are the addons I use or recommend. Any addon marked with an asterisk I have recently stopped using (or replaced with a weakaura),
but will keep in this list for reference. Most of these addons are from Curse, and I use the Curse client to keep them updated.
A couple of them however are from WoWInterface.com.
Some of these addons may also have become broken since 7.0.
Any addons with an asterisk in the title are ones I have stopped using, but others might find useful.
Greatly enhances cursor visibility. Due to a combination of high monitor resolution and crappy eyesight, I am constantly losing track of my mouse cursor. This addon greatly limits that problem. My personal setting is Layer 1: Trail-Holy Bright, Layer 2: Particle-Lava Burst, Layer 3: Glow-Burning cloud, red. (Note: Cursor is currently broken as of patch 7.0 and does not work properly. I have since replaced this addon with a custom weakaura available on my Weakauras page.)
If you want to be informed of nearby rare spawns by being abruptly startled, NPCScan has you covered.
Spams you with incomplete raid achievements whenever you enter a raid instance.
Lets you know what patterns you are missing and where they are acquired.
Tool that lets you run a scan over the course of a boss fight to show addon memory/cpu usage, to see if there are any unusual spikes during combat.
Restores access to removed interface options in Legion and adds a CVar browser.
If you're like me and have far too many characters to keep track of, Altoholic will show you pretty much everything you need to know about your characters across all servers you play on.
Adds a filterable lists of world quests and their rewards to quest log on the world map. So you can easily browse through all the world quests available to you.
Loot tables for everything. Also pops up a small frame of possible loot for specs once you kill a boss, to make deciding on a bonus roll easier.
Yes I use Auctionator and TSM at the same time. I use it for it's super easy to use shopping lists. I could probably eliminate this one and only use Tradeskillmaster.
Allows me to quickly sort my bags, bank, and guildbanks. Features autosorting and autostacking. Far superior to default interface sorting.
Shows an indicator on item icons showing if you have learned the wardrobe appearance of that item. Bagnon module adds support for bagnon.
I prefer DBM over Bigwigs because I am a data oriented person and DBM tells me far more than Bigwigs thinks it needs to. "Bigwigs thinks you're an idiot, DBM tells you you're an idiot."
Automatically types "DELETE" for you in deletion confirmation box windows.
Raid combat log analysis tool. Leagues better than Recount, and a bit better than Skada.
Stops WoW from automatically adding newly learned talents to empty action bar buttons during talent swaps. Useful if you have macro buttons that automatically switch between talents.
Action bar replacement, and in my opinion the best. I use Masque with the Caith theme to pretty it up.
Lets you know immediately when a cooldown is back up by subtly flashing the icon in your face. This could probably be replaced with Weakauras, but who wants to make that many weakauras for every character for every spell?
Allows you to record all the data that is happening behind the scenes so you can see the actual names of events that are being fired off. Useful for making weakauras that track events.
Extensive raid tools addon. Features have waned since HFC, but it still has it's uses. Target marking bar, raid inspect, loot logs, etc.
Allows you to automatically organize groups by role or dps. Create presets to put certain people always in certain groups, or autosplit the raid by ranked dps from Skada/Details.
Alerts me of important goings-on while I'm tabbed out watching youtube videos.
Because wasting time manually arranging the garrison missions of a dozen characters is stupid.
Compacts items on vendors frames. (stopped using this for now because it broke in 6.2)
Compliments GnomishVendorShrinker. Lets you filter vendor items. (stopped using this for now because it broke in 6.2)
Slaps a bunch of crap all over your map to show you where all the phat lewts are. Note: Only install the legion module linked below. The other module on curse is made by a random person and it is not the official module.
Helps you to freak out faster when your health dips low. (I have since replaced this with a weakaura)
Hides annoying junk related to the Quick Join feature.
Also: HideQuickJoinToast
Makes the icon selection frame for macros, equipment sets, and gbank tabs much larger. Also allows you to search icons by spell or ability name.
Tracks your collected wardrobe appearances, and tells you what you are missing from dungeons.
Mandatory for me because WoW hates my three monitor Eyefinity setup. Allows you to place any UI frame anywhere.
Gives you a frame that contains all lootable/usable objects in your bags. Gear bags, AP items, etc. Items are blacklistable so they don't appear if you don't want them to.
Unless I'm grouped with a crappy tank, threat has largely become a thing of the past. I mostly use Omen to see which hunter can't turn off pet taunt.
Adds a plethora of raid tools. Like raid member latency, so you can see who is saying they're lagging in a pool of death yet still have 40ms latency. Cooldown monitor so you can see who fat fingered heroism. Automatic loot/raid difficulty settings once you create a raid. Enhanced ready check. Bunch of other things.
Quick gear upgrade rankings. Must be used with personal simulationcraft weights. Desperately needs support for specifying soft and hard caps. Until then, only use this for quick eyeballing of upgrades.
Mandatory for controlling incoming/outgoing mails. Recipient name autocompletion based on guild members or alts, including alts on other servers. Lets you autopull all completed auctions while leaving other non-auction mail that you might be storing in the mail because of low bag space. etc.
Adds filters to the group finder tool. Great for narrowing down specific pugs and can prevent you from accidentally joining a brazilian pug *shudders*
Works similarly to Ackis recipe list, but for incomplete quests. Mandatory for doing Loremaster achieves where you just can't find any more quests.
Adds a UI to your screen that is a baby version of your talent trees. Lets you single click to switch any talent with no confirmation box. Also shows how many reagents you have on you.
Buff bar replacement. The only other one I've used after using Elkanos Buff Bars for over a decade.
lets you see info about the relics socketed in an artifact weapon in its tooltip
Lets you track your lockouts on all characters on your account. Also shows you which dailies you've completed, such as Blingtron. Also shows how close you are to hitting the instance cap per hour, if you are farming or powerleveling.
Makes the minimap neat and usable. I use a square map with coordinates and with Minimap Button Bag right beside it. Make sure you disable "let sexymap control buttons" options in it's settings if you are using it with MMBB.
Fancy unit frames addon. Similar to Pitbull but more usable right out of the box.
Gives you a simc script you can paste right into simulation craft, without having to log out and load your character from the armory.
Similar to the simc addon, this can give you different outputs of gear in your inventory to sim
Don't even try to tell me you haven't accidentally left one on at some point. Also works with the dalaran teleport ring.
In-game notepad. I keep notes on various things I need to remember, like which xmog pieces I still need to get or when my next raid cache should arrive.
Improved mouse tooltips. Nowhere near as good as Cowtip used to be (RIP), but still far better than stock.
Comprehensive auction tool. I should probably utilize this more than I do, but I tend to keep this enabled only on my auction bank alts.
Puts a frame on your UI that lets you equip/use/track your trinkets. Lets you queue a trinket to put on as soon as you leave combat.
When you go to turn in a quest, it will highlight which item will vendor for the most.
IMHO any healer not using Vuhdo or a custom Clique+Grid setup, is a liability. Doesn't matter how good someone is at healing with the stock UI, they will always be better with addons. The New Yankee Workshop guy might be a great craftsman with basic hand tools, but a high precision CNC setup will blow his ass out of the water any day of the week.
Lets you configure custom alerts and indicators and graphics for whatever event you want to monitor.
