Killing mages with a fighter is easier than all that, go with GM in Katanas, some slots in two weapon style and some slots in flail, celestial fury + flail of ages. If you really want to micromanage put celestial in primary flail in secondary, wait till celestial fury stuns the mage, switch to flail in primary, celestial in secondary so the elemental damage goes through stoneskin, then when stun wears off go back to CF in primary FoA in secondary. those two weapons are the mage killers (and yes I do believe CF is unbalanced it stuns everything regardless of resistances, cept maybe dragons but it probably stuns them too)
