A group os 6 is a good deal... I really do believe that offers the most in group experiments. Just short of getting everything you need in there, but just enough to keep the battle interesting, and get some of the proper classes in there.
I also hope that the raid scene is kept to a minimum. Possibly 3-4 groups. Maybe even 5..but that's pushing it. I personally love to raid, but hated taking 70 peeps to do it. 24 seems to be a good number. Can get the right amount...its not to crazy on control, yet its 24 lives affected by a wipe or a win!
