Thank you for your answer. What classes are you playing in your team?

Is a ret pala fine for tanking the mages focus damage?
1 ret pala, 1 discipline priest and the rest mages, should be a nice team. With this nice buffs, the mages are not oom so fast.
I think, it is more easier to control caster classes, shamanes could be more difficult.
Macros based on /castsequence are very nice.
