Had been running just a Hunter, until this weekend. Why? No clue. Had been doing it since pre-release. Probably the same affinity that drives me towards warrior/fighter-based classes in RPG games. It is the mentality of I just enjoy beating the living hell out of things. However, since I've vaulted some Warlock gear, figured that I would start up a Warlock the other day. And, I do see that my Hunter is likely not going to be my primary for much longer. The Warlock just feels more natural, mechanically - and I feel that I have to be a bit more thoughtful in planning my offense. In short, I think that my Warlock will make me a better player. I don't PvP, so that isn't a factor in any of it for me, though.
