Tip overview

Kill her illusions first so that she can not heal/do dmg/block dmg with it

Pick champions who are midrange or short range since strix will have to move his scope much more to keep up with you. Good champions are Skye, Jenos, Viktor and Tyra. Since they have massive DPS short range and their drop off is not that bad.

Use Defiance point-blank on slow moving or stationary targets followed by a headshot to deal more damage and not give your enemy the time to react.

NEVER engage with Andro, unless you plan on leading him back to your teammates. Annoy him if possible by getting behind but your goal is to lead him to your teamates so you all can bring him down together.

When playing against champions with deployables, use your RMB on deployables, to ensure you don't miss the moving targets. Keep in mind, that RMB can jump through shields , if shot on objects/enemies in front of the shield.
