What id doo is put the pala on the same acc as teh rouge and then 3 shamans cuz then wen your 70 and wana do easy instances you can just stunntank so ya get 1 more dpser and the mobs will go alot faster down

also 3 shammys cuz of the multible totem mania (having wf, agi and strenght on the rouce wiht 3 shamans is just ace) and then just try to get a boomkin to go with ya

and for heroics just get a healing class with ya (guildy maby?)
