Many people ask me what addons on I use. The answer is: too many to count. I have addons for my addons. I have addons that yell at people and ones that yell at me. In fact, my most favorite phrase to use in raid is "Stop making my addons angry!" I love addons! They can really enhance your game and your play. But, If you're having problems with computer lag, the only addons I would reccomend using are Deadly Boss Mods and Vent/Mumble/Teamspeak. These 2 are the core!
List of Addons Used:
-Satrina Buff Frame (to customize the size and placement of Raid buffs and Debuffs)
-Bartender (to customize action bar placement/size and visibility)
-Chatter (chat box customizing)
-SexyMap (to make your maps sexier of course!)
-Mik's Scrolling Battle Text (helpful to know when certain spells are ready)
-Quartz (for customizing casting bars)
Other Addons I use for Raiding : (some I use for Raid leading)
-Recount (damage meters)
-Deadly Boss Mods (everyone should have this! )
-Healbot (one click healing center!)
-Decursive ( for dispelling)
-EnsidiaFails (lets me know who is not moving out of deadly stuff in raid, for example: slime spray on rotface)
-WhoPulled (lets me know who pulled a mob first)
-MasterLoot Manager (easier to dole out raid loot and organize rolls)
-RaidBuff Status (Lets me know what buffs people are missing in raid and who's not buffing it)
-Ventrilo (communications for people who are resistant to change)
-Mumble (communications for awesome people who are cutting edge and don't like lag when they speak)
Side Addons to enhance the game:
-Postal (opens all your mail and puts items into your bag automatically upon clicking mailbox)
-OneBag (combines all your bags into one huge one, fully customize!)
-Questhelper (a must have for leveling!)
-AuctionLite (makes it easier to buy and sell AH items and also to check prices)
-ImpIgnore (lets you ignore more people than blizzard will allow. And also lets you customize the reasons for putting them on ignore!)
