I've been doing archery in real life for four years now so guess who's my "main" character.
But I like all characters. I guess I'll be that kind of guy that has every character. Blizzard did a good job. Every character has it's personality, is interesting and has awesome skills. F.e. I don't like WD very much, but I would play him only because of Locust Swarm/Haunt. It's freaking cool.
