I think that tornado kick shouldn't be something that is never used. I suggest removing the greased lightning requirement entirely. Instead every time you refresh Greased Lightning III you gain a new stack of a different buff. when you stack that up to 3 you can tornado kick and spend that and maybe make a second ability that uses the same stack of 3 to refresh greased lightning.

That way when we were fighting we could tornado kick every 3rd time thru our rotation and when the boss leaves we'd have a way to extend the duration on greased lightning.

All i know is I don't care about how much damage monks do or what their raid utility is. I'm sure all of that will be balanced in the end. I'm just tired of seeing all the other jobs gain new and interesting ways to interact with their skills while we are still doing the same thing we did in 2.0
