I'll just keep it short and sweet, don't need any tl;dr here.
1. Orochi seems to have a lot less guardbreak range than other classes, such as warden. Every now and then I throw a guardbreak but I'm not close enough, but the enemy instantly uses one after and gets magnetized towards me, into a guardbreak I can't counter.
2. Guardbreaking at the same time. I've guardbroken at the same time as multiple characters, and instead of us bouncing off each other, I just get guardbroken and can't fight it. Happened with kensei and lawbringer for sure.
