I think you're greatly overstating how difficult it is to adapt to modified toris. Seasoned players should need no more than 5-6 games to get a good feel for the new set-up. Besides, different mod attributes like dismemberment threshold, frames and gravity can have at least just as much impact on gameplay, but you wouldn't ask for consistency there. Someone who only played wushu will almost certainly fail when he starts to play aikido due to the differences, and those two mods have same exact toris. But with some experience, he can get just as good in aikido.

Anyhow, we can just agree to disagree
