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.
In close range, depending on their timing of popping their Magic Marks on you, Moji can deal up to 1000 damage per second. Never give her a chance to flank and make sure to focus her down after she pops her Magic Barrier and scampers away.
