the game is balanced around using these mechanics.
Agreed. I won't put a judgement on whether or not the specific mechanics are "good" or "bad", but as an example, if the game is balanced around everyone being able to disengage by jumping every turn then to not use jump in combat is severely gimping your combat capabilities.
The caveat I have is if Larian is willing to put in a customizable difficulty slider, then most of these mechanics can be safely ignored and most people can have a fun experience.
