He’s worth it due to MasterSpeedy’s logic. I am biased towards Clones.
KAM makes a solid B level Galactic Republic squad of Padme, JKA, KAM, and 2 others (Cody and Sarge due to them being needed at high levels elsewhere). “A level” being JMK, GK, CAT, AT, GAS.
In what capacity are you questioning worth? Arena, TW, TB, GA?
I realize my B squad is not optimal, but I use Yodas and better options in other squads
