it feels horrible

It feels horrible to be bad at this game with 700 hours. I’m stuck at noob genbu-ruler ranks for 3 month now! I’m losing to players with 50k-100k prowess less then me, they don’t even punish proper or do big combos. Imagine losing to player, who use character for the first time and has only few wins, when you have thousand with only one character. I’m noticing that i don’t use lows as much as i should, zero throws, just offence and sometimes defence, but my defence is bad overall and I’m progressing way too slow in it. It feels like my brain shuts off when i play, and I’m becoming a masher. Maybe i need 300 hours more to get good and consistent, and i definitely need to rebuild my gameplan
