Are you playing 3's /w Shamans? If so don't, the comp is to weak. Ele Shamans lack the solo burst needed.

If you go up agaist a DK/Ret/Ret, DK/War/Ret, RPM, etc... they can all solo burst any one of your guys down. Then it's 2v3 and game is over. 3 shamans is a weak comp in 3's.

5's is possible but only by a highly skilled person with no lag. There is some great rotations with 5 Shamans like Fnova totems, Thunderstorm, etc... But... They still run the same issue with DK's being able to DG you into their burst fest.
