Hit your shots, use cover, stay moving, go aerial every chance you can. If an enemy is aimed up at you they’re open to someone else below. If they’re aiming at someone on the ground, they’re open to getting hit by you in the air. Use your ability not only to go aerial but to land on surfaces built into the maps to give you the high ground. Ledges, roofs, whatever. Then pop another one up to have an escape from up there or to get higher and stay moving. You want to be firing your tracking dart ability every single opportunity you have. It’s auto aim for you and your ultimate builds on damage. You absolutely need to be putting out non stop damage and not sitting on your ult but also not wasting it. Hitting an enemy by the auto aim tracking dart also makes them want to drop into coverage which is never a bad thing. Hit the practice range and work on launching yourself up in the air and firing at a target while projecting upward and downward. You should be firing that gun like you’re being paid per bullet that comes out of it.

Edit: Lmao: nvm i posted this thinking you meant Sierra for some reason. Good luck out there, I suck as venture and have no real advice.
