Possible Squad Arena Team

I agree with you on everything, the problem is that I'm looking for a something i can actually work on. I’ve considered farming chirrut since he’s in fleet, but baze is completely out of reach. I’m only level 72 so getting him even from hard battles is a long way off. I’ve been told chirrut isn’t worth having without baze. Is that true? I also agree r2 has great zetas. I just missed him this time around which sucks. Just not enough time to get a full 5* empire team around and keep up in squad. Obviously without r2 i won’t get cls either at least not for a while and i’m still quite far away from having the characters for him. Again i’ve only been playing for 2 months almost exactly now and I’m looking for a squad i can actually farm that will be viable for a few months till these legendary characters come back and I can add them to my collection. I’ve been considering getting jyn and cassian and possibly k2so (easy gw farm at 15 shards a day). Are those characters worth working on?
