Moji has a hard time aiming around Vivian's shield, so to deal with her, flank. Be weary of sensors and If Vivian placed one in the flank route, take it out, wait a bit and strike later once Vivian assumes you've left and busies herself.
If Strix catches you, you're dead. Run Fluffy 5, Symbiotic 3 and Harmonious 5 to save yourself from a headshot and a 2nd bodyshot. Or run Fluffy 4 and buy Haven if you're confident he won't land a headshot.
Expect the combo whenever he uses Thrust. Use your Magic Barrier to negate his burst. You can run Fluffy 4 or combine fluffy 1-3 with blast shields to make yourself a 4 hit kill with directs unless Drogoz is running Fusillade.
Ruckus is safe from CC when ulting, so unless he's low at the end of it, save yours until he finishes. If Ruckus pops his Emitter, try to save your Magic Marks until it ends, or continue to rip though him if you have the upper hand.
Terminus beats Moji in melee range. when fighting a Terminus, fire your primary as far away as you can to avoid his Axe. Shatterfall is reactable and you can usually scamper away. If not, the momentum you gain should be enough to keep yourself safe.
