Modding Kanan under CLS

What rank are you in your arena?I am running the same team except for Zarris instead of Kanan. I am in an old shard and can get into the 70's.

I hold 75-40. I have zeta on him, #crunch, and 2 on CLS. It's a really fun squad due to all the TM gain and Ezra calling assists. Going against CLS is nice because he gives Kanan health every hit but unless he is gettinng hit by debuffers he dies quickly.
I'm running a health set with protection primaries, speed arrow and speed secondaries but he seems squishy.
Should I stack Defense since CLS gives him +50% and he gives himself Defense up?

Defense mods are underrated, especially when combined to a leader or arena mates that can increase this defense. I can recommand you all defense mods with speed arrow and secondary, and primary protections (triangle, cross, circle). He will have 80% defense under CLS lead, making him very resistant.
