Beat Conor once. Close second fight. I mean the first fight Nate pretty much Homer Simpson'd him but whatever...
I have great realistic fights with some people, it depends on the player. Some guys just stick to your face even when you keep smashing them. High pace fights are annoying for sure. It feels kinda rock paper scissors given how early you have to use head movement, rather than reacting, but it is VERY satisfying when you smash one of these guys that won't relent.
