Fellow at the FLGS last night let me proxy Gonk and Dengar on my YV last night. My list was:
Bossk
+Veteran Instincts
+Gonk
+Dengar
+Outlaw Tech
+Engine Upgrade
Syndicate Thug
+R4 Agromech
+Twin Laser Turret
×2
He was playing a Palpatine Shuttle and a mini swarm of unique TIE Fighters.
He smartly went after the TLTS first, and I was having trouble connecting attacks, so I traded both Y wings for Wampa after a few turns of fire (other than one attack when I dealt 4 damage to the shuttle from Range 3 because Bossk triggered). Not a great start for me, but at this point, I had Bossk completely untouched and 3 shields ready to be recovered on Gonk, against 3 untouched TIE Fighters and a gently damaged shuttle.
I pulled it out. Got the shuttle down to 1 but then it had to come around and waS out of my hair for a minute. He pursued me through rocks and had to break up, so I could at least guarantee that in most turns he couldn't attack me with every ship. He did pull a coupleasure if highly skilled turns and caught me in the net with nowhere to boost, but like I said, Gonk got me through it. Over the course if the game, he dealt ten damage to the YV, only one of which was a hull damage. The extra shields protected me from quite a few critical hits, as well, so those last 2 HP could well have been direct hits. And with Dengar and Outlaw Tech, I could make essentially any maneuver and still boost or Gonk without sacrificing a modification.
The Scum large ships have been characteristically weak for a while, except for IGs. Gonk is admittedly limited compared to Rebel regen options, but is a HUGE step in the right direction. Can't wait till its actually legal.
So Wave 8, then...
