Arena squad advice

Is dooku zetaed? Wedge lead with dn, chaze and one other is a popular set up.

He is not Zetaed. I have only 10 zetas. Haven't zeta anyone yet.
So Wedge lead with DN, Chaze and.....EP or Rex?

I can only 2 star (barely) that node for Sith Assassin.
I don't have R2. I will be ready next time and get him 7 stars.

Good thread I am in a similar spot, except lvl 79 and I have been running a R1 squad with Boba in place of K2. But I am bit bored and finding the Rex rise annoying for this team and on D they blow as they live off of the expose and on D the AI toss shock grenade in to TenUp.

I have been thinking of switching to a Rex (L) 7*, DN 5*, Chaze 7* +1 team of either EP, Boba or Jyn. I like having at least one person that can stun on the team to deal with Kylo's and Dooku's and StH. Or going a Wiggs, Chaze +1. My R2 is only 5* I'd love to use him in these teams his kit is great with a stun on basic, smoke screen and the AoE burn laying down a debuff for DN.

I'd be interested to see what you ended up deciding on.

I just got Rex to gear 10.
Think I'm going to go with Rex lead, DN, Chaze and EP.
Then try maybe Wedge lead with Rex, DN and Chaze.
I'm at work now so I'll try later tonight.
I only have Boba at gear 9 or I'd add him. Need to gear him to 10. It will take a while though.
