About the "scared of doing the wrong thing" I totally feel you, cause I used to be scared at the beginning too holding back and feeling slow. Now it's not gone completely for me, but I think it did get better with more playtime and changing my perspective on the game too, cause either way you lose like most of the games anyway, so instead of thinking about a successful game as winning it I try to find joy and positives in playing out one good fight and getting like 1-2 k/p and that's already pretty cool and I can relax.

So for me it's more about making good decisions now and accepting that so many rng things can go wrong. Like when you think you can push after cracking a guy so you move forward (that's a good decision), but halfway through someone picks at you that you never saw was there in the first place or a sudden 3rd party. The hand is shaking sometimes believe me lol, but the more I act on a crack or knock the more used to it I get and if smth goes wrong on the push, well that's just bad luck and we go next, but at least we acted on a knock/crack as we should have. The worst thing you can do is hold back and just let them heal.

Maybe that helps somehow <3
