How to remove potion Delay & Use Items during skill cast in PvP

[dragon2000]

Hi everyone!

Does anyone know how I can remove the delay on potions and items in PvP? Also, is there a way to allow clicking/using multiple items or potions while a skill is being cast? For example, with Royal Knight it works, but for other classes it doesn't—when I click potions or use curses during skill animations, nothing happens.

Any tips or fixes? Thanks a lot!
