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 you see trix shooting towards you and getting invicible try to shoot him(and make him vicible again after 500dmg)spray/shoot/splash dmg near the place he just turned his stealth on
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.
