The skill cap was lowered by removing it, it literally made kenki management matter, cause if you over used your filler spender you wouldnt be able to use it.
Just because it was always used doesn't mean it was a bad thing, aetherflow is always used before energy drain, should we remove that?
Life surge is always used before a big hit for dragoon, same thing.
I dont think comparing to pvp is a good idea either because if we go to 4 buttons in our rotation in pve i'm quitting instantly lmao, that works in pvp cause encounters are short, but the game would be so god damn boring with that few buttons
