i'm also absolutely missing the tank role here. clerics can tank. tanking in t1 or t2 is no problem at all. and despite all arguments over clerics arent good at raid tanking, i just tanked 2nd and 3rd boss in greenscale with absolutely no problems at all. it is possible although we still lack magic mitigation ...

saw 2 of my roles in there...

I am using the Warden(31)/Sent(30)/templar(5) for my dungeon heals...
I find that using all 3 healing souls is inefective, but the templar gives you the break free... used this more in dungeons than you'd think

I am using Shaman(34)/Justicar(20)/Inquisitor(12) for everything else
I use a 2 handed weapon with spell power and never run out of mana, don't do loads of damage, don't take aggro from the tank, hit everything and heal with every swing(me and my group)...

i havent tried an actual ranged DPS role yet... but might try one like that... been using those 2 roles since beta 4... and they have just gotten a lot cleaner to play with...
