The MP restore on aetherflow is one of those situation where it will get better as gear progresses. Energy Drain, on the other hand, will lose its value the deeper into the expansion we go as it is a set amount based on level. They can buff the potency or cast time, but the MP cost in relation to max MP will feel less of a burden as ilevel goes up so asking them to reduce the MP cost, instead of looking into other areas where sch suffers, might hurt sch in the true long run.
