What about giving both enchanters a skill to spread (its the word i hope

their power around. Something like mana burn for wizzy but with feeding effect. Make it some fair recast. Now you may feed a group as a coercer without having to worry about pwr gain which you will flow away next sec.
Or just remove or lower the pwr back part of mana flow. Because its not VM what is broken. Its Mana Flow in its current state. Using sprint to get rid of your pwr is not rly of an issue. Its fun and removing it will make me sad panda because thats the way to enjoy my class. I have to do what i should with so much reduced pwr pool and its fun. Easy mode ftl in this case imo. Hard mode (or just not easy) is ok. But insanely imposible mode with coercer mythical (or mystic mythical which is fucking us up much more than the coercer one) is not the way to go. I say, give us the ability to get rid of our pwr fast with some kind of dps and/or utility. Maybe change mana flow to fit these specifics but leave VM as it is.
