In terms of technique, Toribash hasn't helped me one bit. but as for flow, I think toribash helped me there. There are certain moves in Toribash that c'mon, we all know can't be done irl. But the concept of flow, I was able to take that, and modify it so I could move a little better. I'm not saying I don't look stupid at times though, I just like to experiment with different things.
As for if an irl martial arts background helps you in Toribash, I really think it does. I've been training for the better part of three years when I started this game, and I spent a couple months doing the sports everyone else does. Then I got into sparring, and realized that alot of the moves you can do irl can be done with an in-game round of sparring (modified ofc, Toribash is an unrealistic game after all).
In short, I think tb helps with certain things. trying to learn martial arts from a video game is stupid, but taking concepts away from other people in a martial arts based game? Not as stupid.
Also, please remember I'm talking about concepts, not any sort of real skill
