Divine, I could probably bet on SE just adjusting the amount of mana summoners get per point of piety to fix our mana issues. More mana reserve increases the mana regeneration in combat and increases the return on Aetherflow. I would go so far as to say that SE will adjust this so that between the incombat mana regen plus Aetherflow we will come out just below the theoretical sum of all dots, shadowflare and ruins cast in a minutes time so that we will need to use energy drain but not as often as we currently need to.
