HELP!!!

It's a baby yoda convention!

Redo your mods. Looking at your clones (which are your best team), you should have +100 speed on all of them. Arrows should all be speed mods. Don’t level up any mods that don’t have a speed secondary or for arrows primary. For your arena team, mods should have a minimum speed in the teens, 20’s would be better (though hard to get early game). If you average +15 each, though, with +30 on the arrow that’s +105 speed, which is decent in the early game. Mid-late game you’ll want +120 or more.
For toon specific mods, Fives passes on offense, health, protection and speed when he sacrifices himself, so his triangle and cross mods should be one of those categories (offense is usually the best choice). I would also probably give him either a speed or offense set, as your other 501st will have plenty of health after he dies. Rex should be all speed. Echo can be either offense or critical damage. Until you gear your arc trooper better he should be speed as well, since he relies on Fives’ stat boost to have any damage output. Shaak Ti can be a speed/health (or tenacity) set with protection primaries on the cross/circle/triangle.

I have one

Farm geonosians, nighsisters, sith empire, separatist droids

Unlock CLS and Chewie and c3p0

Well then this might help. https://swgoh.gg/p/878138847/

I suggest finish your Geonosians to 7* first. Gear level: at least G11-12, Alpha and Poggle the most important because of their cleanse abilities.
Then farm Separatist droids.
Then or paralel you can go to finish Padme and her crew: Anakin, Ahsoka, Kenobi + 1 GR.

With this way you will have a good defense team (geos), a good Revan counter (sep droids), and a solid Drevan counter (Padme). If not yet, you will definately have to face Revan and Drevan teams soon, so I think "This is the way" :).

Pick a squad.. finish it.. your nearly there with clones, do them (your gg has 5s in the second slot, move him to 5th) the as @Olderaan says geos seps padme will get you the most bang for your buck..

Also, for the love of god, stop using mace for fleets, he’s literally the worst fleet commander.. tarkin or ackbar are much better..
