Yeah, I'm pretty stoked to swap to an ARC in our current campaign. At PS4 I'll have Predator, Engine Upgrade, Vectored Thrusters, R2-D2, and 3-PO. All I need is Biggs' ability and super tank is ready to fly.
The HWK is fun in heroes too, but for it to be balanced the attack shuttle has to either cost more or lose a mod slot or something.
I also like the idea of Zs flying in pairs. Instead of a mod slot, you just buy an additional ship every 4 levels or so.
I love the idea of someone flying a formation of 4 Z-95s as their "ship". They would be their own section, and fly very differently than any other ship on the board. I think the economy for these ships would have to be changed a bit (Engine Upgrade is great, but can you afford it 4 times? What about EPTs?), But I think it can be made to work.
