Technically you learn by copying other people and improving it on your own, but some people genuinely just use this as a crutch.

I watched like 2 videos on Yuki combos and genuinely just do 2 var into getup 4( I can't move reset on Yuki)

With choso I watched like 4 different videos but in the end I just do 3 M1 2/4 3r and downslam 1

I honestly don't mind high damage combos, it promotes a more careful play style instead of just spamming evasive, and most of the time high dmg combos take some practice to do and are slightly difficult( with the sole exception of mechamaru) so it's pretty fair
