Not sure I should be mixing with foxes, it wouldn't go down well with my kind. However, I'll give it a go.
Firstly, I'm not sure what your priority in the game is, but I see you've put a lot into bugs. So, I'm guessing PvP is important to you.
For Zetas Ahnaldt101 has a very neat spreadsheet, where he classes all the zetas. This spreadsheet is bit behind with the new stuff. However, if you go to youtube and search 'swgoh zetas ranked' you'll see the spreadsheet linked in the description. The spreadsheet has lots of other good information, like omicrons for example.
I see you haven't put any Zetas on Thrawn, good job. I'm at 12 million and haven't given him one either. The one that sticks out to me is Kylo Unmasked. With the Zetas and 6 dot mods he can be a right pain to get through. I'm also remembering that without his Zetas, getting SLKR is very difficult or impossible.
Looking down your account I see Savage and Jedi Master Revan. Savage, with his omicron is an exceptional GAC character. Not just short-term (like Geos), but a forever relationship; you'll never get tired of each other. If GAC is important, invest in him. I have his Zeta and Omicron. Jedi Master Revan is a super solid minor superstar. You can build a jedi team around him, and later on he can swap into a support role on a jedi mega-star team. He has 3 zetas, they're all worth getting.
Similarly, I see you've recently unlocked Commander Luke Skywalker. He, like Revan have aged a bit in the game, gone a bit grey just above the ears. However, form is temporary, class is permanent. Again, all the Zetas and build a team around him. He's needed for future unlocks on the jedi path too.
Connected to this is your Chewie and Bounty Hunter team. Bounty Hunter teams can be a royal pain to use. You need to mod them well. However, you have the components of a good one, and you'll need them better to 7 star your Chewie. Also, Bounty Hunters have awesome ships. Bossk, is the most accepted lead. Fennec vs teams with damage over time. Aurora Sing, although not a great character, can have the easiest 'bounty pay-out' to obtain. Obtaining your pay-out is the vital on BH teams. The Mandalorian and Greef tend to be the stars of the team. You're missing a lot of Zetas here, check Ahnald's spreadsheet for zetas that align with where you want to go with them.
I see you also have Captain Rex up and running. He makes a Phoenix team very viable too. I see Padme, Moff Gideon, R2 as another potential team.
I also see that you have geared some 'undesirables'. I see Lando, Clone Wars Chewie, Jedi Consular, Snow Trooper, Talia, Hoth Soldier all with some work put into them. Unless they have a definitive use, don't put any effort into your undesirables.
Lastly, and possibly most importantly, work on something big. Work towards unlocking big characters in the game. Preferably, ones that lead on from your last unlock.
To conclude:
Level up the big characters you've unlocked. (CLS & JTR)

Plan where you go next and what you will unlock. However, aim big
