I like rebels period. Overall, rebels sucks for been overpriced and can't have that many upgrades.
I been thinking a lot on "How can Rebels give of a lot of fire power yet at low cost as possible?". Y-wings might be the answer.
I have invested a lot of time and money on getting 4 Y-wings with Dorsal and titel - right now, I lack just 1 Y-wing.
The list looks like this:
Grey Squadron x 4. All are equiped with Title, Dorsal Turret (3p), Flechette Torpedo (2p) and Guidence Chip (0p) - that's 25p x 4.
The key is to get all for Y-wings to focus on 1 Jumpmaster at a time. If all 4 Y-wing has 1 Jumpmaster in it's firing arc, a lot of damage can be done.
If 4 Y-wings are at range 3 to 1 Jumpmaster, in fire arc... Y-wings will be able to use target lock and use Flechette torpedoes. 4 x flechette will let you roll 12 dice. 1 hit is a garantuee thanks to Guidence Chip. Hopefully, Jumpmaster will go down on one 1 round. At range 2, Y-wing will combo with primary and dorsal. In total it will let you roll 16 dices (4 dice for each Y-wing, 2*2) - range 1, 24 dice. (6 dice for each Y-wing, 3*2).
If you play with 4 Hired Gun (Scum Y-wing), you could try with 4 x R4 Agromech. Stay at range 3 from just 1 jumpmaster, to spend focus and get target lock. Save the target lock. Next round, the one jumpmaster with target lock on, get to range 1 or 2. Add 1 focus. First attack, primary, spend target lock if you get 0 or 1 hit. Spend focus to get a new target lock. 2nd attack "dorsal". Do the same thing accept can't spend focus.
