Eventually you get enough resists that you can basically stand in stuff and get healed/take no damage and you get immunity/high rolls to most CC so you pretty much ignore everything but physical damage which doesn't do a whole lot, while at the same time doing 3times the damage mages do per round due to Rage and Oath of Desecration(which is a mage spell though but still better spent on warriors).
Use 2H weapons though, they should do equal damage to mages even early on. Especially Scythes once they start dropping have crazy damage ranges, you can increase the damage of every metal weapon at Whetstone wheels with 1pt blacksmith(the dmg increase is static so 1pt is enough, can use an item to give the point when you do it). Also helps a lot if you use your mages to buff your warriors with Oath of Desecration/Bless.
