I'd appreciate Greased Lightning getting a serious duration buff. Stop Monks from rushing off ahead of the tank in dungeons because they can't bear the thought of losing those stacks, and proceed to royally screw me over in trying to pull.

I'd also appreciate a savage nerf to greased lightning, something like "need to build six stacks for half the effect, and only lasts 7 seconds". But that's probably me being exceptionally bitter at the moment over a Monk rushing ahead of me in a dungeon because he couldn't bear the thought of losing stacks, and proceeding to royally screw me over.
