If your jedi can take the first 10 nodes in GW, then this could help your sparatists on the last 2 nodes:
@Old_Ben12345 I just checked your profile on swgoh.gg and it looks like you could have some instant improvements to your separatists:
You are level 80 but some of the separatists you're using trail at level 77, 75 and even 66. If you take them to level 80 those characters will have a higher chance to land their debuffs - both in GW and in all other game modes. Those debuffs are essential for your team.
You should also train their abilities some more. I know omegas are still scarce at your level (apply them where you benefit most, f.ex. on B2's Mow Down) but you should train your team's abilities all the way up before omegas. F.ex. Magnaguard could gain higher debuff chance on its basic and Asajj could reduce TM more with her special.
You can also improve your team through mods. Speed is essential for most characters (less so for B2 because of its unique). Several of your best speed mods are not equipped by your arena team:

But ok, maybe your jedi need those good mods to get through the first 10 nodes.
Good luck in GW.
