I have a 68% winrate with Jett in 35 matches. I don’t bait mates to get kills. I entry site, get first kills etc. Should I just instalock her in maps I play with her, or is that a dickmove. What do you guys think?

So, a while back I saw people aiming low whenever they're spraying with the vandal or phantom. And I started doing it too, which got me a bit more kills. But I'm not sure if something changed with an update or something but that ain't work...
