here's something i found in a comp game by accident. When you use knives for jett you can updraft once and then use breach's ult which is going to throw you higher into the air which can give you a lot of vision on a sight.

What is it about almost every Killjoy players that I meet that turns them into menaces after changing sides? They place their turret into the most annoying places, plays like rats and somehow still alive for post plants. They play like shit...
