Which rogue one toons are best?

Rogue one was my first real arena team. Jyn got both of my first two zetas, and was my first g12. I love rogue one, but unfortunately they’re pretty useless outside of TB now. They had been a decent TW squad at first, but the last few metas have added several new squads that blow them away. You’re using the right 5 right now. If you get K2 to g12, he can easily have 80,000 protection. With his zeta (I wouldn’t recommend it, but you already have it) after being hit 20 times or so, his protection will be around 100k. Jyn’s leader zeta -which is mandatory- will then be healing him for 5,000 protection every time he gains a buff. When he gets hit, he counters and gains taunt (5k there) and if it’s a crit, chirrut gives him a heal over time (up to 10k now), so he’ll be nearly unkillable. His daze helps immensely in TB as well. Cassian is where the majority of your damage comes from. Using his two specials consecutively can land upwards of 5-6 exposes on one person (i’ve seen his second special land 14 exposes) and a couple on the others. Definitely worthwhile. Chirrut and Baze speak for themselves. I think to reliably go 6/6 on the last day of TB, you need a to have Jyn and chirrut to g11 or better and zeta jyn’s Lead. One tank should be g12 and the other close to it, and Cassian can probably get by with g9-10. Jyn will just have to revive him every few turns. But -as always- the higher the better. With jyn’s zeta, cassian’s unique will be healing protection across the whole team (more on k2) at the start of each round. If you decide to zeta Cassian it would increase that healing further, and may allow you to get by with less gear. Outside of TB, it’s not a very good zeta, though.
