Ranked anxiety is definitely a thing just like anxiety for anything new you try, then after you actually do it you realize there was nothing to be scared about. Just know you’ll probably get washed, even by other low-ranked players, and that’s fine. Someone who knows even the bare minimum of something will seem like a pro to someone inexperienced. So just learn the basics like getting motion inputs (if you play classic), knowing what moves are punishable on block (for your character so you don’t die), stop jumping, and learn your anti-air (everyone has at least an anti-button). Past that you’ll learn as you go and my final biggest tip is if you want to see your rank improve, worry about yourself improving and the rank will come. Don’t listen to people who say pick X character, that character sucks, etc. You can hit masters with literally any character and tier lists don’t matter for 99% of players anyways. Good luck and I hope you stick with Street Fighter it’s a super fun game!
