I have read the pve shaman wiki... nice job and thanks. I have searched and watched vids and such about heroics and 5 shaman teams. I gather that 5 shaman can run heroics with good gear, i have seen some vids of them taking out boss mobs and such.

My question is can a 5 team of shaman do all the heroics or are there some that they can't do? Can the 5 team of shaman handle all the boss fights or are there some they can't do?
