So after several sets I've realized that I'm just doing the same block strings and I'm getting counter hit by an assist. So I need to learn how to hit confirm off of two hits. I think I'm realizing that people can react to a block string by calling an assist and that is what seems to be getting me killed a lot. It's not neutral, it's not resets, and it's not my inability to react it's my stubbornness in just going for a 3 hit confirm.
This is definitely something that is important to be able to do vs good players. I don't think I see people calling assists while blocking that much at high level play as DP assists become less common, but high level players will DEFINITELY be able to reliably pbgc punish blockstrings that are too long. With double I had to put a decent amount of time into confirming off of just c.lk c.mk (or c.lk c.hp at longer ranges) since 2 hit confirming didn't really come naturally to me but it has more than paid off.
