@ i90 I find I don't really have MP problems unless people are eating lots of stuff they shouldn't and/or dieing.
I guess that's the benefit of good gear, but prior to that it really seems that the MP regen is insufficient. At lower ilevel for t4 or extreme primals you are pretty much going to need manasong at some point even in a fairly smooth run.

WHM has a dual issue of needing to worry about MP and enmity when SCH's design means they have an easier time with both of those. That's not really a bad thing, but it would be nice to have better tools to deal with it.
