Your revert did not include the following. Destroyer's healing spells/conversions are not affected by encumbrance. So they literally heal for 2x as much as they did on the real revert. Encumbrance does not effect the casting time of their healing spells meaning catching a destroyer casting a heal and being able to punish them off out transitioning them or being able to throw 2 1/2 spells at them during their heal self/witches brew typically allowed you to significantly out damage their heal if you landed spells or close splashes. These 2 alone make a retarded difference. Destroyer's don't have to waste time casting unburden. Self Buff's allowed you to have higher stats than Destroyers. Slashing debuff and other debuffs are still nerfd Rage still exist's which ONLY nerf's mage DPS, destroyer's are unaffected. The heal is the same for both destroyer and mage. The same for spell heals as well when that use to not be the case. Destroyer's had to enchant their staff with casting time ridding the benefit of either magnitude or mana efficiency. Did the revert include grouping mana shield with double jump? I haven't logged in since before the patch. But all of these were previous micro buffs that changes throughout ROA indirectly buffed destroyers.
