some more info, seems that CTraid will be implemented in next patch:
Also coming up in the patch is something tentatively called "Leadership UI," a raid and Battlegrounds feature available to the leader. Right-click on any mob and a drop-down menu will pop up. Here, the leader selects icons that will appear above the mobs' heads and be visible to all group members. This way, you can prioritize targets without having to type or say anything, and it's better than other communication because (1) people sometimes forget the plan and (2) things can get hectic really fast. There's also a "raid warning" channel. When you chat in this channel, the text will show up in a bold white font in the middle of the screen for all people in the group. In a BG, this is great for coordinating rapidly to respond to things like flag capturing, base protection, and other things. Lastly, the leader can initiate a "ready check" from the raid group window. When this is triggered, all players in the group will have a prompt pop up that will ask them if they're ready to go.
each class will have his own epic set with frost resistance:
And their will be an epic set for each class with frost resistance, designed to combat Sapphiron, a frost wyrm boss in Naxxramas, the upcoming, gigantic dungeon coming soon to an Eastern Plaguelands near you.
prolly release date:
As far as release dates, Burning Crusade is still slated for "late this year" and 1.11 is planned for June, with a Public Test Realm release at the end of this month.
