if you go with your mouse over the resistance, you will see that Affliction is also included in domain resistances. But that resist makes you almost invulnerable to the strongest spells. Mages supposed to do more damage in exchange for that higher damage their denfense and HP are lower. But as it is now they have both disadvantages. low damage and low hp, and this is just a HUGE unbalance. This is CLEARLY a cap bug. Sure as you might prefer melee you like that mages are clearly powerless now.
