Thank you, I've been stuck on 7* Thrawn for ages thinking i needed to wait for my Rex to hit 7*. First battle with the mods, unlocked him and used him to 7* R2D2.
I prefer zeb over sabine. I have him modded for offense and potency, and if the potency is around 80% or so, with Rex’s guaranteed tenacity down and dazes, landing a stun is almost guaranteed. It really helps with the tm train and the enemy never gets a turn, especially on offense
The reason for Zeb being "all over the place" with his mods is that he's labeled as a Tank. He doesn't have the natural Offense to hit hard, so those mods just bump it up a little. He's slow as a "Tank", so Speed mods don't really help him much, either. If he was labeled as an Attacker or a Support, then the mods would have a greater impact.
I just opened mods and noticed that you can't put any mod you want on a character now, I had a bunch of health mods and nome of them could get put on my Sabine
Kanan is generally agreed to be a very important part of the team so if you had to farm just one then definitely him however both Kanan and Ezra are on the same Cantina node so if you're planning on using both you should farm that node but if you don't want Ezra you can also farm Kanan from the squad arena store both are very easy farm though.
