Teir 4 - Special Op 3 strategy?

I'm surprised it took so long for anyone to mention the Nightsisters, Ventress in particular. In stage 2, all you need to do is debuff Baze (and everyone else) with Ventress and then stun Jyn with Daka (or Ventress when it's her turn again). Then it's just slogging through the HP. I actually don't have Daka so I used Tusken Raider instead, just for fun. Sadly, my underpowered squad could only do Tier 1-3, but I could see a better prepared set of Nightsisters owning this event.

Instead I went with First Order for Tier 4. Not my best squad, but this was a great chance to try them out after their second rework. Kylo stunned Jyn to prevent revivals, FOTP donkey punched Baze. But I did end up losing FOST in round 2 because the AI hates FOST and gave him a beating in round 1.
