There seems to be quite a few ways now to get multiple attacks from a single ship in a round, and this number is going to increase again with Wave 8.
While upgrades like Gunner and Luke Skywalker were once seen as "insurance policies" for large, expensive turrets ships (if you're spending around half your squad points on a single ship, you want it's attacks to be reliable), some of the more recent incarnations such as the Twin Laser Turret and BTL-A4 title can be fielded in numbers, and are unsurprisingly proving to be very popular.
Currently available:
BTL-A4 (title card)
Cluster Missiles (secondary weapon)
Twin Laser Turret (secondary weapon)
Corran Horn (pilot ability)
IG-88B (pilot ability)
Gunner (crew)
Luke Skywalker (crew)
Wave 8:
Phantom (title card)
Dengar (pilot ability)
Looking at the list, and it's quite a competitive set of upgrades - only Cluster Missiles and Luke don't see regular use. Do you think it's fair to say we'll see this trend continue, and more ways to get multiple shots enter the game?
