I propose the buff be changed to suit it's original purpose - substantially bolster a single target's mana replenish for a limited duration. In practice, this should let us effectively perma PF a single target for the full 50 something sec duration (this feels fine given the substantial 3m recast with no reset potential). Imo, changing the refresh rate to every 0.5s, and the amount of power to 1%-2% would be great, as that would allow us to make sure an important target (healer, fighter, or potentially enchanter) isn't completely oom during a scripted power drain, or just a heavy powerdrain instance in general.
