I know this one's a bit vague, but it really comes down to your playstyle; skilled Androxus players rely on split-second timing. Try and use this to your advantage; usage of specific parts of your kit at the right times can help you a ton.
Assuming Buck hits you at point blank with all his pellets in the head, he will need 3 shots to kill you.(2.8s) This will never happen. You can knock buck down to 500 HP with the Daggers+Pounce+Daggers combo (about 2s). Easy kill from there.
You do not want to duel Maeve as her combo WILL one shot you. Stay away from where she likes to play unless you have an ally who can kill Maeve first with you.
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.
"Smoke screen" blocks line of sight of Turrets, so they can't shoot anyone. You can mitigate Barik’s damage for 5 sec, just with one skill. Right timing and "smoke" placement is key factors.
