wanna make a room?(once my connection gets back to normal) I've been training with Seks for the exact same problem haha.
I'm pretty sure that was just you. You're giving up as soon as the match begins, so I wouldn't be surprised if it's nerves that's fucking up your dashes. are you inputting the dash more than once? Half of fighting games is the mental game and because you keep telling yourself you'll fail you never do things that will help you succeed. Stop doing that to yourself. I may suck at SF4(Hell, I suck at this game too) but I never tell myself that I'm destined to lose once a match gets underway. Even if someones 2000pp higher than me I may joke about them probably kicking my ass before the matchs tarts, but once its underway I play to win no matter what. What you're doing is pretty much creating the outcome(a negative one) before its even happened. Stop it.
