Hmmm interesting responses. Well first off I've seen in testing from mobile gamer and ahnaldt101 that subbing nest made a huge difference facing nightmare and synergizes well with the expose.
The reason why I called GK weak is as people said, he usually gets fractured or isolated so his mass assist doesn't usually go off. He's great don't get me wrong. We all love GK, but he can be a brick in this lineups.
I do believe that RJT, BB8, GK, R2, and Enfys is probably one of the best combos. And yeah subbing thrawn for GK probably could help on offense. I'm a massive fan of wampa and I really wanna get him to work with this lineup because of the expose synergy.
I was thinking maybe JTR, R2, BB8, Enfys, Wampa. R2 should smokescreen wampa off the bat which would be devastating.
