2 elite, 4 regular I assume Koopa, that's how I normally run Sorin

only 2 copies of an elite but unlimited 4 non elites, got ya.

Not unlimited. 4 regular is the limit. 2 elites.

I think after Jabba drops we might have some very scary Sorin lists.

Sorin + Adv Comms

2x eProbe

4x Probe

2x Jet Trooper

Zillo

That's 9 activations. up to 12 attacks. All of them are Vehicles or Droids so all can focus off Sorin, and stun. The 4pt jet troopers can Overrun and have a decent focused attack.
Probes can all recover, Jet troopers can negate surges. Zillo helps keep everything alive.
Could swap one set of jet troopers for 2 officers. The troopers also let you take grenadier as there aren't many good droid cards. You might want the officers for some of the good leader cards... more focus, new orders etc...

Either way, that's pretty terrifying.
