Do what sorry? I'm not quite following what you mean,
Do you mean they could chain sways, make you whiff then blast a TD fake to get a switch?
Cause they can't do that easily, there are horrible input registry issues on chaining TDs off sways, it wouldn't be reliable.
TBH. Given how easily and quick you can switch stance, I can't see TD fake spam being a huge unbeatable tactic, I think the person doing it is more like to get KTFO.
Edit: That said, I'd still like to see open stance clinch and stuff. I'm always switching after stuffing a shot due to the stance mirroring, it'd be a nice QoL update.
