I can never pick just one favorite - I love playing "large burly dude with a giant axe", but I like casters too, and then in Rift I somehow wound up sidelining my axe-wielder and caster in favor of my rogue. Though in fairness my rogue gets to teleport around dodging attacks and healing herself by killing, which makes for an awesome solo spec. My axe-wielding warrior turned out to take way too much damage and I've only just recently found a decent solo spec for her that lets her keep the 2-handed axe, and I just never got a handle on the caster at all.

I have no idea how I'm going to handle this in The Secret World, where one character can eventually learn all weapons and combat skills. Maybe a hammer-wielder who does some magic on the side.
