As the title says, why?
Every other hunter has at least one but Cad gets none? Seems pretty disrespectful. Especially when you have a perfect spot (Stun Glove) to place a Zeta on him, making him actually effective against Jedi. Maybe even add something else to that ability as well.
I'm just saying Cad deserves a zeta and it just looks weird that he's the only hunter without one.
Edit: I waited to post this until after Zam's rework went live to see if she would get one, and she did.
CLONE HELMETS!! Now let's get Sabine her epic helmet.
