Let's see what happens once Imperial Vets comes out. Won't the Gamma Squadron Vet w/ Deadeye be even worse? Or possibly just different?
Just different.
I'd expect to see Gammas with LRS and Crack rather than Deadeye - what makes Deadeye so good is the combo with R4 Agromech.
Or Chimps and Jonus Shuttle.
Realistically though I'm expecting Vets to bring the Defenders, and a few Bomber Buddies. The actual offensive bombers I suspect will retain their current meta standings, more or less...
