Well that's a good thing to know. So there are different ways to cancel.
However here's my list for reloading/cancelling:
YY
Pros- fastest, good-looking
Cons- If done incorrectly may leave you open, leaves analog stick, removes ads for a period of time(bad for snipers)
Sprint
Pros- Medium speed, can continue to run after enemy
Cons- can leave cover(if ur in cover), can give opening, kinda ridiculous?
Shooting(I've actually never tried this so correct me if I'm wrong)
Pros- can hip fire enemies faster, no need to mess with the analog stick
Cons- maybe the slowest, not practical(Personally I wouldn't use it...)
I'd probably use YY more than the others because I'm so used to it however I may use the other cancels possibly.
Tell me what you would rather use or help me update this. I probably missed a few things...
