Try to avoid parkour as much as possible with the leap
Also use leap when falling or being mid air
The key is to try to get a good start to get ahead from everyone else and even deaths. A good death would try to kill as many people with one trap, not to go for the one ahead
To gain momentum at the start, go a little behind the wall and time your sprint perfectly so that when the wall opens you’re already sprinting out while everyone else didn’t have speed trying to run but hitting into the wall
Hope this helps!
