If i were to level 2 other classes i wouldnt be 5 boxing them. It would either be sticking with 3 shamans or going for 5. I was gonna make 2 other classes because i don't have one of either yet but then the thought of upgrading to 5 shammies now has peaked my interest. I would only want to run instances during the levelling process as well as questing.

I'm speaking about in pvp, is 5 way bette then three in bg's? And how much harder is 5 to manage then 3 in arenas?
