This is a PvP addon for World of Warcraft - Wrath of the Lich King (3.3.5a)
Shows your target's, and your focus's cooldowns, as cooldown icons.
The addon detects spec based on spec talents, the cooldown numbers of course can vary, but I have used the most common talent setups as a base, and the worst case scenario.
Target, Focus, Self Diminishing Return frames. These are also cooldown icons, with a number to show the level.
Shows Interrupts around you as cooldown icons, it shows everybody's (for example if there is 2 Warrior around you using pummel, then it will show both Pummels).
There is a combat log bug in the client (Well probably it gets some unexpected data from the server) both int the TBC and WotLK clients. (Although in WotLK it happens rarely.) Practicly your combatlog stops processing any new events, a fix is implemented to work around this.
OmniCC - This will put cooldown numbers on the cooldown frames (and of course your spells on the actionbar).
