Which brings me into the classes. There are really only three specific class TYPES, and I'm even stretching for the third: you either A) hit enemies with a sword up close, B) shoot enemies with spells from farther away, or C) shoot enemies with a gun or bow from far away, then hit them when they get close, the hunter being the "C" in this.
There are nine classes to choose from: three mainly-melee classes - Warriors, Paladins and Rogues - four caster classes - Mages, Warlocks, Priests and Shamans - and two hybrid classes - Hunters and Druids. I say "hybrid" because, while I'll admit a Shaman and usually does melee a good deal, both the Hunter and Druid switch between close-quarters combat and long-range casting on a daily basis, while Shamans usually use spells that inter-change with their whacking away.
