potential 10m setup

[creativefla]

hi guys
my guild is a 10m raiding guild, which has all 10 unique classes in the raid setup (tank-druid warr, dps -lock mage hunter dk rogue, healer- shaman priest pally). from your experience in 4.2 PTR and stuffs, what is best possible raid comp to go? there are some things that boggles my mind like;
-claims that this coming raiding tier favors multi dotter dps
-mana tide nerf (with increasing pally healing cost, i wonder if we need replenish, because we dont have any lol)
-less kiting (maybe our dk can go tanking, druid go heal(replenish)/boomchicken, priest/shaman go dps)
gear wise, we have the gears to start, we're just wondering whats the best way to start thats all. and we could not afford taking same classes in a raid because our guild just small lol but we're making our raid as flexible as possible.
this is an open ended question, theres no right or wrong i just need opinion =) cheers <3<3<3

We have been fully focusing on 25-man and so on 25-man setups so I'm afraid I can't really comment on optimal 10-man setups. Of course certain classes always get the job done better than others, so try to build your team around those while brining all the necessary buffs.

Also, our thoughts on what's gonna be good and what we'll be focusing on is something we like to keep to ourselves since we are so close to the race.
