There's a Topic like this in the X wing forums, so I decided to get the ball rolling here and take it a step further with top 5 favorite squadrons too.
1. Rebel Assault Frigate. This ship is a jack-of-all-trades-master-of-none type of ship, but it looks cool and had managed to remain a staple for us Rebels since Wave 1.
2. MC30c. This ship may only have 4 hull, but it's got a ton of firepower, it's fast, and it's shields are amazing for a small ship. The titles are the best defensive upgrades (IMO).
3. Liberty cruiser. It may not be a big hit with most Rebel players, but it looks so beautiful, and it's always a blast to use, even if it goes down. It's still got the single strongest shield in the game too.
4. GR-75. Great support ship. Not much else I can say.
5. CR-90. Specifically the A variant. It's been the fastest, most manuverable ship since the very beginning. It's great with TRC, and the 2 point Jaina's Light is grossly undercosted (IMO, and not that I'm complaining).
1. Shara Bey. Natural counter 3 with crits counting as hits? Yes please! I also like squads that, when they die, their loss doesn't affect other squads (like if Blount dies early, Zs lose a fair amount of effectiveness)
2. Ten Numb. I love B wings, and unblockable damage is always a plus. You just have to get a Blue crit to activate it.
3. YT-1300. 7 hull Escort and Counter?! Again, yes please! Best escort for B wings.
4. Corran Horn. Snipe and Rogue make a nasty combo, and with Yavaris and Adar, you can assassinate your opponent's other aces pretty quickly.
5. Dash Rendar. Rogue, Bomber with a black die, and rerolls when you're at distance 1 of enemy ships and squadrons. Sounds like a deal to me.
