Well you’ve got more then enough replies but I’ll add my ten cent.
I actually do the exact same thing you do, I started to main Ibuki (who I’m currently thinking of changing because my god dropping vortex makes me mad) and for all the combos I had learnt, I went into the match and stayed away with kunais, and basically tried to punish anything and everything with TC10 (which is silly). And after playing around 50 matches with my friend that night, I went back into the training room and just did 1 combo, over. and over. and over. and over again. Then i went and watched a few replays of myself (because as always when you watch you can pretty much tell what the other dudes gonna do half the time and you know how to punish it, but when you play its completely different) and I found an instance where i could punish that with my combo. Next day I was fine, and played ibuki quite well. My recent change has come from understanding how to start a combo, realize it’s not hitting (being blocked) and ending it safe instead of autopiloting into a neckbreaker from muscle memory.
So I don’t think it’s frustration because lets be honest, you’d stop playing if you were Mangry. Whats causing it is just the lack of experience playing with that character in a Real match, not against a training dummy. My friend has this problem on SFxT. When we’re in the breifing room he can do all of his combos like the back of his hand. never drops one. constantly doing it. We get into a match and he’ll just outright punish someone with a Jab. and leave it at that, I don’t know if it’s the feeling of pressure, or the desire of wanting to win but he plays a lot differently when he picks paul and just wings it lol.
It’s more likely nerves then frustration, My advice, just grind out like 10/30 matches online, win or lose everyone, but DON’T~~~~~
1.Care about the match. No mashing Ultra on wake up bcz i ar mangry, If it’s because the guy keeps jumping at you All. Day. Every. Time. feel free to teach him not to.
2.Play to win, instead play as if you’re watching someone play and attempting to learn from it, and take time to make decisions. Okay you see him Shroyuken and by the time you say to yourself “Yeah i can punish this” he’s already on the ground blocking but do that enough and your hands will go “Okay master time to punish”
Weirdly enough Street fighter gets a lot more annoying when you Actually try to train and play it, when you don’t you don’t care because you know nothing. When you do and you drop a combo it hurts, especially when you lose because of it.
Oh and on a side note, how do you actually feel playing Cammy? I’ve noticed that characters for me come down to feeling. When I first started playing characters, characters i played like Ibuki/Ryu/Dan/Gief/Balrog just felt right, they didn’t feel confusing and i wasn’t sat there doing nothing (all be it barely punishing). But characters like Makoto/Fei Long/Guile/Cammy/Rufus When I play them it feels wrong. And that’s where most of my frustration comes from. If I play Fei and I know I’m supposed to cr.lp into rekka and Every time i get a chance to punish i just constantly mash lightpunch and then realize I can’t special cancel from a chain. It pisses me off, Or playing Cammy and having a good 2/3 combos down but not understanding how to get in because everything I do just feels unsafe and wrong. Understanding that it was the characters that were doing that to me helped a bit aswell.
Anyway, I think i added more then my Ten Cent. Hopefully all the replies have helped you in some way
