I play fighting games since 2001.
Dont want to sound cocky or anything, but i have a basic understanding on how "fighting" works.
In this particular case i was having troubles on a mirror match where i was outplaying my opponent.
The duel would end with him at 5% and me dead.
Im pretty sure if i had the same gear as him i would win. 370 to 400 is a huge gap and is very noticeable from my understanding
