Honestly I think the 25 man raid is more likely to happen than the 10man solo raid..

Im definitely in with my 5 chars (or less depending on how many solo chars are online):

Disc/Holy Priest
Destro Warlock
2x Ele Shaman (maybe respecc one to resto)
Tankadin (GS around 5k.. should be fine for the first tries.. He could respecc to Holy too if we have enough tanks)

Cmon guys lets do this :P
