This is how I deal with it.
- Biggs goes 1st with his secondary on Chaze and brings help down to half
- Boba goes for an ability block and I have some good mods where his potency is very high so it usually ability blocks everyone
- STN then taunts
- Use AOE from Lando and Wedge
- If Baze isn't dead then Boba's execute on him
- Focus on killing wedge
- Rest is easy
I'm only level 74 and the highest level that is competitive is 77 so I don't have to deal with omegas yet (maybe my strategy will need to change in the future). Further, in the case where Boba doesn't his ability block and I lose, I usually only fall back to #10 so it's easy to get back to #1 without spending crystals for additional fights.
