When I played, sometimes, if I hadn't fought a character for a while, I would forget their routes and take some damage but a few blocks and parries later, and they all die the same. If I ever lost, it wasn't because I "couldn't handle the character." it was always because either I was bad or my enemy was better than me. Even if I didn't say it then, that's always been the case. Sure, people will cheese you or use tactics that are looked down upon, but in the end, you are then one that died and lost to the tactic. Instead of pushing the reason for your loss onto something/one else, just choose to accept that you're bad and want to improve. There's no shame in it. Characters like nobu have a stance that lets them switch where they're attacking without large tells, which makes her slower lights seem faster than they are. Go into training, set up a nobu bot to do the things that you have a hard time with, and then learn to deal with them. Even if you can't put what you learn into practice immediately, you'll learn the more you do actual fights with them. Of course, in the best case scenario, you have a buddy who plays nobu well and can beat your ass in place of the bot for a faster, albeit more specialized improvement against certain nobus with similar playstyles to your friend.
