GearScorePlus – when you mouse over a character you get a tooltip that shows how many incorrect gemming and enchanting choices they’ve made. Will auto-initiate a kick vote for any DK with a spellpower enhancement. An extension, GearBusted, will warn me when a dpser zones into a dungeon with armor that’s below 50% repaired. I hate when the hunter dies (from pulling aggro) and then says “lol sword broke need to rep”.
OmenEnhanced: Puts up notices every time a player who is not the tank uses a taunt or threat-generating move (Ret pally using Hand of Reckoning because “it does damage”, hunter pet on growl even though “I already shut it off jerk”).
RecountTheFailRotation: Heck, I don’t know what abilities ought to make up a DK’s dps rundown, but my theory is that “Death and Decay (50%), Melee (45%) Heart Strike (4%)” isn’t right. How about a damage meter that shows me what they should have been doing?
DeadlyBossEasilyPredictedDamage: For healers only, mark the players who are about to be standing in the easily dodged fire/spikes/whatever so I can pre HOT/shield/whatever them.
RangeAlert: let me know when anyone is so far away from the fight that they’ll be aggroing the pat behind us while the rest of us are fighting (hunter and mages only)
AutoIgnoreIdiots: auto-add people to my ignore list before I get grouped with them. This includes any dps who is going to fuss about how they don’t want to be bothered going after extra bosses and anyone who has ever dinged 80, queued for H COS, and, while contributing less than 800 dps, asked more than once if we were going to make it in time for the drake. Or any dk who has thrown Army of the Dead on the Saurfang fight. (bad memories)
DontCursive: Clearly mark when people in your party have diseases, curses, poisons, or magic effects that you can remove. This is so you know to whine at the priest who is not removing curses, the druid who is not curing diseases, etc.
Any other suggestions?
