I posed this in another thread at some point(not like there aren't 4578 SMN threads) but one thing I thought of was to maybe give fester a chance to proc a free energy drain. This would leave SCH unchanged, and if given a high enough chance(I was thinking maybe as high as 50%) would both help a bit with MP and increase DPS slightly. I think there needs to be slightly more done than just that, but it could be a start.
