Try to burst Zhin. When he uses Counter, run to a safe distance, then open fire like hell. Additionally, his attacks are very inconsistent, so if you are a character with a burst type weapon, you will usually win.
Force an Androxus into a long range fight. For example, if you are playing Kinessa, and an Androxus sneaks up behind you, teleport to a distance, and open fire from there. He will either have to fight if he does not have Nether Step or run.
Never get close to Ruckus. 1. Your damage will be to pitiful to seriously hurt him, and 2. Ruckus's damage will completely shred through Grover like paper, and Blossom will not be effective whatsoever. Moral: stay far from Ruckus.
Kinessa's hitscan sniper rifle leaves Drogoz with little escape, where he is in the air or not. 2 well aimed shots can easily kill Drogoz. If Drogoz tries to bombard her with rockets, she can teleport away with Transporter.
Sha Lin's basic attack an Planted Ability easily shred through his shield, and allows Sha Lin to easily kill Fernando. Additionally, with Wrecker, his shots deal even more damage, which easily melts Fernando's shield like butter.
