It this legit?

Really? Is this possible?
Nute and Nest are G11, rest are G12

Lysandrax

GAS can beat that team in 1 turn, so yes

DarjeloSalas

What level is his GAS?

If he’s relic 7 I’d say that’s perfectly possible if he took out Dooku first

Antario

GAS can solo many teams. So do Malak and Nest.
That being said, the team on your screen is not a typical Gas solo victim team. I definitely won't take the chances if the team is on the same relic level like GAS. But obviously it is not in your case. Probably most of the toons got one shot by Anakin counterattacks.

Overboss

The battle lasted 13 seconds which means they all died in 1 aoe. I guess it is a question of gear/relics at this point.
