Sorry I cannot really contribute to this post as I have not started yet, but I can't decide on what classes to roll....my ideas are:

1 Priest, 4 Warlocks.

1 Priest, 4 Mages.

5 Druids. (Which I think might be possible....ie, my main tanking and the rest healing/dps-ing....who knows)

5 Shamans. (obviously)

Anything melee of course is almost impossible as I've learned, and it makes sense.

One possibility I've been interested in is 1 Priest, 2 Warlocks and 2 Mages...like Xzin said, similar spells but harder to control.

or even 1 Priest, 3 Warlocks and 1 Mage (or 1 Warlock 3 Mages)

But those may not be very feasable. I'm looking forward to posts in this topic.

(I plan on focusing on both PVE and PVP. Perhaps more PVP, I love arenas!)
