Why does my stance change every time I'm punched?
It's very annoying.
actually its not like that. you cant change stances while you are getting punched and have to switch in between the hits. some other things might cause a position change too, for example when your attack gets dodged or someone walk around you.
I think its because you can't block with your back to the opponent. I guess. I honestly dont know, but I DEFINITELY agree; its super annoying. It's hard to initiate a specific counter-attack when my stance keeps changing.
To answer your question, we would need to see video accurately depicting what you're describing.
