Zetas order

Right well just going character by character from the list:
TFP: N/A
Cad Bane: N/A
BAM: Has two zetas, Leadership probably not that useful since his lead isn't used much that I know of, Unique Zeta is good but you'd need a scoundrel team which you don't have atm and since I'm guessing you just need him for RC it's not really needed
Rey Rqs / Rey: You seem to already have the zetas and order in mind
Cal: Guessing you mean big cal not just baby cal, either way I'm not too sure about that but I'm gonna say that you could probably only consider Cere/Baby Cal zetas since you don't have a team for the rest of the reqs and you could mix some UFU together if you needed
Wampa: Gonna need at least one zeta for the omi, second zeta can be nice but not sure it's rly needed
Dark Trooper: Luxury Zeta here, will depend on if you think you need it or not
JKR: Probably Lead, Unique and then special in that order
That's pretty much all the zetas that I could help with, I'm not too familiar with the rest except for CLS squad, Han zeta is definitely needed but not sure where on the priority it is

Idk how big the gap will be between Rey and SLKR, but if you’re going to have his kyros and relics mats saved up, I would skip all of the above and get his zetas.

Highest priority of what’s Listed JKR > CLS anything past SLKR is too far to think about at the moment.

Both Revans really need all of theirs - they’re mini GLs. If you’re doing JK Cal, he also is in this category.

You only need the one on Wampa and the rest on that list can be ignored until JKL and Jabba/BH

I mean baby cal. He's going in Rey's team.
