CT Raid Assist (required raid addon)

Screenshot of CT Raid Assist Official Homepage: http://www.ctmod.net/downloads/
CT_RaidAssist is your all-around raid mod. It can report hp, mana, buffs, and debuffs of anyone or everyone in your raid. You can set it to notify when someone is debuffed with specified types as well as notify when buffs you can recast fade. It can show 'MT Targets' which allow you to specify MainTanks's which all users in raid can then see. When shown, it will show you the target of the person set as MT. It's a bit similar to the Target's Target function though with this, the tank doesn't even have to be your target.












KLHThreatMeter (required raid addon)

KLHThreatMeter is like a damage meter, except it records your threat. By monitoring all the abilities you use and checking your talents, armor set bonuses and buffs, the addon can recreate the threat list of a mob. This makes tank transitions simple, and allows DPS to maximize their damage without pulling aggro.

Decursive makes your life easier, it clearly shows you who is afflicted by something you can remove, this is done using "Micro-unit-frames" (MUF): a micro-unit-frame is a little square on your screen that changes of appearance according to the unit status. If you click on a MUF, it automatically cast a cleaning spell, the choice of the spell depends of the mouse button you click, Decursive manages the button mapping automatically.

Titan Panel (core only)

Titan Panel is a user interface that creates horizontal bars that can hold other modules. Game, performance, character, and quest data can all be displayed using different addons to the Titan addon. I've removed all the "included" modules that come with Titan and posted ONLY the core Titan Panel. You may add modules as you see fit.

It provides you with methods to identify the bargains at the auction house (the percentless and bidbroker commands) by identifying price trends and then finding items that will buyout or bidout for less than the trend data suggests should be it's correct price.
