I noticed that on consoles the button to grab is different than the one to punch enemies. In PC both are the same button (the left mouse click), the only difference being that you need to press the button longer if you wish to grab something or someone. I have tried changing the grab button to another mouse click (I have 6 mouse buttons), but each time I did that, the punch button would reassign to the same one as well, still only needing to ''press longer'' for the grab option.
Please take a look at this DEVs, it's unfair for console players to have this advantage, it really does make a difference when I'm trying to hold something/grab and it does the opposite, it also makes the Ball games harder.
Just simply let us reassign the button without the punch reassigning automatically as well.
