It's time you started being the main character in your games.
You can buy left-to-right and the build should work!
Dash-Jump -> Kinetic Pulse engage has more reach than people expect.
You can Charged Melee or shoot after an opponent is knocked up.
Berserker is optional. I take a lot of damage and play like a lunatic so it works for me. Otherwise build Basic Magazine if you want something easier to use.
