If one of these is on you, you CAN'T regen end over their cap. With rk3 reprieve on I am stuck at 29% end until it is off. I hit staunch recovery once with it on and only got 29% end, I have hit it in guild hall and end never goes over 29% until I click it off. I am sure this is affecting all endurance users and not just us.
That's not really a bug though, since it's working as designed. The design in that case is poor though, yes. I can see how they could change reprieve so that Staunch Recovery strips it off, but it will require changes from Sony part.
I'd /bug it in game w/ a request to code Staunch Recovery so that it first checks for HP/mana/endurance caps and removes them. I just did one as well.
I'm guessing this will take code support, though it should be easy, so it probably won't happen for a matter of months.
