Alright I see. I don't use dip much outside of prologue since I have better things to do with bonus actions usually. It's not very realistic, but next to jump and shove it certainly isn't too strong.
Perhaps they should simply not allow dipping on fire until you coat the weapon with grease, maybe that would suffice? Making it too complicated would not pay off, at that point might as well remove the whole feature
There is no mechanical reason to even have that feature. Most certainly not as a core mechanic that needs its own dedicated button in the UI as opposed to say the "dodge" action. Which IS a core mechanic that SHOULD have its own dedicated button in the UI.
