One person will have themselves blocking while buffering in the direction of the opponent's strongest throw while on defense, but said opponent will be anticipating this and simply go for a directionless throw...Things like that. lol
Oh, I'm sure they do. They thing that was kicking my butt the hardest was wiztick using Brad Burns. He'd be like: "poke-poke-huge grab" and I just kept eating it. I imagine that when you get good at buffer-escaping, they switch things up.
Just do your best to buffer them whenever you block!
And I don't know if I mentioned to you before, but in higher-level play, people will try to out YOMI-one another with throws..
