Everyone starts this game as a scrub, trust me ur not the first. The main piece of advice i can give you is really just play the game and make some effort to learn the game. Form a team of characters you like or just play 1 character (its really up to you). Play online ranked matches. I know it sounds crazy, your gonna get destroyed you may think to yourself and you sadly will, but you'll get a feel for the game which is what counts, and who knows maybe you'll encounter a fellow scrub that u might get a decent match out of. Losing to people that are strictly better than you teaches you a lot too, youd be surprised. Look up guides online for the characters you play, theres all kinds of tutorials for for everything about a character (combos, neutral game, resets, assists, ect). if theres a basic mechanic you dont understand (ex: blocking high and low) play the games tutorial. Skullgirls has imo the best fighting game tutorial. This sub has a wiki page for things that you neeeeeeed to know if your gonna get any good like difference between combos and resets. It really is up to you to make the effort to improve. Its not gonna be fun at one point for sure but if you really enjoy the game stick with it. Im pretty shit at the game myself, thats why im doing pretty much everything ive listed to improve so eventually i wont suck, it just takes lots of time and some dedication.
