I don't think three "archtype" characters really cut it.. There are a number of popular archetypes... Let me throw some names out of the strategy guide for you..
Warrior
Mage
Archer
Berserker
Spellsword
Assassin
Battlemage
Rouge
Weaponmaster
Necromancer
Just a few basic ones for you.
Personally I play a Weaponmaster/archer/assassin type character, with magic for added utility. Using whatever is appropriate for the situation at hand.
