Your options:
Full Melee... 1H Sword, 2H Sword, 1H Axe, 2H Axe, 1H Mace, 2H Mace, Dagger (7)
Full Ranger... Bow, Dual Wield Pistols (2)
Full Caster... Staff (1!!!!!!!)

Can we get some wands, crystal balls, magic rubix cubes or something?
~ Only one option is boring.
~ Only one option is frustrating when you have to wait longer than other 'classes' for a chance at an upgrade.
~ Only one option is probably contributing to the fact that most of the builds that I see people using are Melee or Hybrids.
