I had unlimited MP on my THM before the update. I had Siphon MP which can drain MP from the dead, and you get a bonus from the dead, plus Damnation, and my 10 minute 50% MP restore. If anyone is going through that much MP in a few seconds, they're being a little wasteful.

I think some of the spells should have their costs cranked up, or it should be turned down some. What's the point of having MP if there's no threat of running out? There needs to be some reason to be careful managing it. Even using a few spells on MRD, there's now no threat to running low. Plus it's always restored after a leve. It just needs to be rebalanced a little. I think spell costs should just be upped by 50% (expect Ancient Magic. 100 MP a flare seems fine)
