I see your point, and we all react differently. When I get hurt (as long as it's not major) , I tend to get a lot more feedback from my senses, which helps me execute in better form. Plus - if I get angry, I get calculating. Not to hurt the other player, but I start planning 20 steps ahead instead of just 5 or 10Actually, that's when I stop, because if I fight while on adrenaline, someone's getting seriously hurt (probably me) and I don't want to do that.
For me, few things compare to being thrown hard into a well-executed breakfall that doesn't hurt at all.
