I started with 3, quickly made it 4 and played 2 teams of 4 ele shaman for a good year or so. Now about 2 months ago i got a fifth account to put my druid on. I have yet to do anything while playing all 5 characters activily.

I just can't be bothered to play 5 charaters, i like it relaxed, which is much easier with just 1 class then going for multiple. I'm pretty sure i'm one of only few, but just wanted to make you think about that
