there was some guy ranting about soccer on a bench offscreen, just ignore him

Hello everyone

I got Uni2 around a month ago mostly because of the songs but also because I wanted to try my luck in fighting games. Turns out that I'm struggling real hard with the game and I'm losing interest in the game. Every match feels the same, I get one attack off, I get combo'd and 12 seconds later the match is over. I tried training and missions but I can barely do that at 25 speed let alone at 100.

My question is there a real reason to continue grinding and getting zero enjoyment or should I just cut my losses?
