Any thoughts on the Dreadnaught Hunter upgrade for Epic? It's a powerful ability that lets you really mess with a Huge ship. However, it's also 10 points and puts a huge bullseye on anyone who's carrying it, while also doing nothing to normal ships.
My thoughts on some of the better candidates:
Rebels: Corran Horn and Gavin Darklighter. Both are pretty durable and evasive. Corran can use the double tap to focus the target down, and Gavin's pilot ability has a built-in crit conversion. Luke also has some potential here. Dreadnaught Hunter is a Command upgrade, so you can't take it with Veteran Wing Leader. However, if I'm reading these correct, you CAN put Veteran Wing Leader on Wedge, then put Luke in formation with them alongside Biggs and a Selfless Red Squadron Veteran. Wedge can then help knock shields down before Luke fires.
Empire: Maarek Stele was born for this. Each time you deal a crit, draw three cards and choose the best combination of crit and precision damage. You can protect him by hiding him on a Gozanti until he gets into deployment range, and I5 is pretty good for avoiding a getting PS-killed. Defenders are also great candidates, as seven health behind three agility with the ability to focus and evade makes them very hard to burn down. I would not put it on Vader, as he usually fires before the shields would be dropped.
Scum: Xizor is probably their best contender. He can fly in formation with some other brave meat-shields, making him a very hard target to take down. Anyone else either too big or too fragile to be an option.
First Order: Kylo Ren is really the only choice here. Quickdraw wants to be a Wing Leader to minimize shield damage, and none of the other named Silencers or SF pilots synergize with the upgrade.
Resistance, Republic, and Separatists: I see no good options, but would love to hear disagreements.
