They also do much higher dmg than melees and they also dont need to walk to the mob to hit it but still pve is not an issue .the problem comes to pvp ,many pvps at gvg are about whill will run out of mana ,mage parties usually run with an extra burner and u give them clarity passive on top?a change similar to dagger to "steal" some mp from mobs when mobs die seems more logical to me.
