Vet Han teams?

No tank and a Zarriss and/or GK makes Lando useless, better off with either GK or CL

CLS lead for assists to help VHan/VChewie health steal.

I think you could:

Thrawn(L), DT, Han, Chewie and Shore/GK.

Boba(L), Chewie, Han, Thrawn, GK

GK(L), Barriss, Chewie, Han, R2/DN/Thrawn

None are as effective as a similar squad with better synergy, but probably still fun to watch Chewie smack CLS around.

I'm not filling two spots on my team with characters who don't benefit from Rebel specific CLS lead or R2's number crunch. In fact, not only would they not benefit, they would lower R2's overall stats and the resulting boost for the rest of the team. Everybody suffers. All so that Chewie can have turn meter when Han dies? I don't think so.

So
Just to to let everyone know
I barely clesr top 500 in my shard
I have 0 zetas
And I do not fight zeta teams
