The build sounds weird because no assassins... And while it is occasionally annoying to be locked out from time to time... Combat this is the best. The player must be tank only because they maximize skill usage and tanks can spam taunt for eternity. The thing with taunt is you get armor (it's like a overshields and MUST for end game play) While you spam armor (overshields) iron bull is the melee champ of damage. You ensure that all enemies are aimed at you only and close so each of bulls swings hits everyone 2 mages is another must. 1 Mage just doesn't heal enough but 2 offers sustained combat. Each has Heath tree... But the "special" tree(you get that later in game) The knight enchanter Mage special tree gives you a slow down and buff/debuff field. The rift Mage tree gives you huge debuffs in a area. With this, basically you are in the eye of the storm with every enemy attacking your overshields while your Teamates are spamming aoe debuffs
