Moving my comments from the squad and character synergy section here:
His hp and protection are absurdly low. He basically needs to modded completely for hp/protection to be remotely viable in arena. It feels like he had been tuned based on flat bonuses via mods initially but seeing that flat bonuses are no longer available on primary, this is looking like a design flaw. I'm assuming the gifs above are from the dev testing done. You can clearly see that this (and presumably most of the testing for cody) is pre-nerfs on mods. The number of health pips on those clones are no longer possible to attain.
He is basically a slow glass cannon without any survival skills. Every other toon that falls into this category has been proven to be useless in arena (think darth maul). Without mods, he easily gets 1 shot by rey. With mods, u get him to turn 2 if you are lucky.
Also, defense on his leader skill seems like an afterthought. This could have been something more useful to increase survivability overall which is a recurring deficiency of most clones. Again, this could have worked with flat defense bonuses (secondary flat defense bonuses are too marginal to have much of an impact). An interesting idea I had was to swap his defense bonus (which is largely ineffective) out for a revive chance based on the number of clone allies alive. Something in the ballpark of ~60% revive would require opponents to choose to focus cody or the other clones first, indirectly making him more survivable. Unlike other self revive toons (HK, Boba), Cody actually can do some damage and poses a real threat if not dealt with.
In raids, he does reasonably well, having almost cleared P1 as leader in a full clone team.
Considering the cost to attain Cody (and full clones), it feels like he is missing a key piece to bring everyone together. He needs something to give them a bit of sustain. Lately it feels like there is no advantage to buying a p2p character. They seem to be held back too much and often featuring unnecessarily complicated mechanics.
I have a maxed clone team which I have been playing for some time now, usually with JKA and I have thoroughly tested many different team combinations. JKA lead is the most arena viable with the correct mods, and Cody lead is the best raid set up.
@CG_Kozispoon, please consider this feedback on this iconic SW character. I sincerely hope that some tweaks will be made here.
