Try to keep track of Androxus ult, particularly when your ult is either ready or active, as Andro can burst all his ult shots on you to kill you and/or destroy your drones.
With the 'BOOBY TRAP' talent, keep your mine activated near you, if Andro (or any other enemy) comes from behind you, it will do initial damage, alert you, and a little knockback making him lose some precision.
