Yeah, most PC games don't support analog buttons for keyboard input that have that in the first place either.
As a left handed player, KB/M is frustrating. I either have to play with the mouse in the hand I don't want to use and accept accuracy loss, cramped hands and a wrong layout (can't do this anymore, hurts too much after 10 min.), or remap every single key in a game. And boy does it get tiring to remap keys. As an added bonus some games won't let you use keys like ";" for game play (*cough* Elden Ring) so you can't do a WASD-esque left handed mode. Oh and a lot of gaming keyboards have their matrix setup in such a way that you can press WASD simultaneously, but this isn't true for keys on the right side of the board and of course, no reviews or product pages mention this. And I'm not even getting into the problem of getting a decent left-handed capable mouse. Fortunately most PC games that support controller somewhere else support it on PC now too.
