whats wrong with 2 warriors? just give them both huge swords and start beating the living daylights out of stuff, of course if you wish to change you can still do so throughout the game. i originally had hero as warior and DK as mage, but my hero has over 300mana and one good spell (lightning) and a huge sword (typical i know of the warrior types but hey..) and my DK has become an archer specialist (but lacks a really good bow) with continually changing spells (i like to try them all out) though currently using hammer. just devote the 5 points per lvl on what you really want you dudes to be, its not how they start, but how they finish.
