When you are boosting and you have to put your carry pants on so high that it makes you look like a grandpa. Yet you still fail
asd
sure.
open the console and write the following commands.
bind mwheelup +jump
bind mwheeldown +jump
now practice like everyone else does. or you could download a script or something like ahk (autohotkey) and put risk getting your account overwatch banned.
but really, practicing it isn't really that hard. get into a kz server where it's easier to hit bhops and start practicing there. once you've got an idea of when to jump, start doing it on normal servers, either 128 tick or 64 tick. 128 tick is said to be easier, because it's more consistent, but personally i find it easier to bhop on 64 tick.
also, listening to music like shawn wasabi or busdriver will help you alot.
