To me, the health regen slowdown felt more significant. Could be due to my safe fall training. 75% of r33 is still viable, but from what I read, it'll be progressively reduced to make cooking more relevant.
It's not really an issue for me. I just heal myself with heal spells and use passive stance to gain my focus back really fast. So the regen rate being nerfed is kinda irrelevant for me.
