Any Suggestions for a new Arena team?

Parableman

I've been having a hard time getting a team that works in Arena with the new meta. I was running this team before the change:

QGJ lead (73, 6*, gear 7)
Luminara (72, 7*, gear 8)
Poggle (73, 7*, gear 8)
IG-86 (73, 7*, gear 7)
Geonoshian Soldier (73, 5*, gear 8)

I was able to get into the top 200 most days for several weeks, until the level cap increase, and then it was harder, and I was slipping most days into the 300s and occasionally into the 400s. Now I'm not able to get into the top 200 at all but have come close, and I'm slipping into the 400s much quicker. I'd love to be able to get into the top 200 every day and not slip below the 300s.

I have a broad roster, because I like to unlock characters and use them in Galactic War, but a lot of them are just not viable in Arena. I've also been restricted a little in who I can farm, because I've been focusing on a Jedi team, and I'm still working on getting several of them to 7* (using Cantina battles for Barriss and then JC when she's done, JC and Barris on hard nodes as well, QGJ on Cantina shipments, and Eeth Koth on Arena shipments; my expectation is that I'll be ready for the 7* battle if it returns at the end of the month with the raid update, but it limits who I can develop).

Other characters I have (in decreasing power):

Barriss (71, 6*, gear 8)
Jedi Consular (71, 6*, gear 8)
Mace Windu (72, 6*, gear 7)
Eeth Koth (65, 6*, gear 7)
Yoda (71, 6*, gear 7)
Phasma (71, 6*, gear 7)
Darth Sidious (70, 5*, gear 7)
Royal Guard (71, 4*, gear 7)
Old Daka (71, 4*, gear 7)
Rey (71, 5*, fear 7)
Poe Dameron (70, 5*, gear 6)
FOTP (65, 3*, gear 7)
HK-47 (58, 4*, gear 6)
Nightsister Initiate (46, 4*, gear 6)
Boba Fett (52, 4*, gear 6)
Old Ben (70, 4*, gear 4)
Chewbacca (53, 4*, gear 5)
Ahsoka (55, 3*, gear 6)
IG-88 (47, 4*, gear 5)

Any thoughts on what I might do in the short term to get my Arena team to be more successful in the new meta and what I should be working on long term to develop other characters to replace whatever team I settle on for now?

That. There is no diversity anymore so just develop those guys until they nerf them.

That's good for the long haul. Any suggestions for right now? I'm not sure my Royal Guard can cut it, and I know my Dooku can't. Rey is good on offense, but I'm not sure I want to leave her in there overnight. Maybe the same is true of Daka.
