With good game sense & map awareness you can counter Androxus Ult. Use your ultimate directly on him (if possible) or walls near him. Hitting terrain will trigger AoE Stun and interrupt his ult. Good aim required.
Run through "Siege Shield" to deny Ash’s zoning. When shield is behind you, its no longer useful for Ash & her team. Be careful and don't do that trick on low health - Ash might burst you down.
Currently, Talus' Ultimate is really weak and other than CC immunity, any swift movement can overcome it. Nimble (Literally just 300 credits) can overcome Talus' ultimate.
