I believe drinking potion should be a full action as well
. There is also perk unique to rogues that later down the line allows rogues to use items as bonus action. Larian is heavily damaging uniqueness of classes - not a surprise as they preferred somewhat classless system for D:OS2.
Doesn’t changing weapons take an action? I am pretty sure it did in my recent playthrough - or is it just picking up weapons after getting disarmed?
I didn’t find potions too offending, but shove is too powerful. I think I wouldn’t mind it as much if it was much weaker giving chance to disengage from one character, rather then instant kill chance.
