I've played every class except bezerker. I usually have one main and a few alts going as I tend to get bored easily. I no longer raid nor guild but just play with a few friends who have similar interests to me. I don't enjoy the raid game, although I was in a top 3 raid guild up until elemental PoP.
I just enjoy playing / exploring / hanging out with a few RL friends and accomplishing what we can that way. Which is sometimes as simple as trying a new duo or trio out and seeing how far we can take it etc.
Anyway, sort of off the point of the thread, but I thought I'd answer.
