How useful is Quivering Palm in EE Stormhorns?

[Carpone]

If you're running EE Stormhorns quests with a Quivering Palm capable monk, what's your DC and success rate?

My DC on Quivering Palm is anywhere between 56-60, depending on what stance i keep my monk in...Once I ran Stormhorns on EE, I stayed in water stance mostly due to increase to DC's of all tatical feats....In EE Stormhorns with a Stunning Fist DC of 68, I have a success rate of around 60%, give or take..With Quivering Palm, I would say my success rate is MAYBE 20%, except on elementals which then is around 50%...No exact on numbers so just guessing but taking the best positive results as a response
