I think that if someone discovers a move he can use during a match, kudos to him/her. Eventually others would pick up on it and also use it. It just makes the rest of us want to learn these moves to be more competitive. Besides, I think they are cool.
I never heard of it until it was patched out 
you can still super slide you just cant super bounce and fall anymore. it was fun and it honestly shouldve stayed in but it did break maps. i use to fly across the map litterally to an enemy so its a lil unfair
I miss flying across the map like some sort of projectile
No was another way to juke people bring it back
