As much as I don't think all is lost for the Rebels, I appreciate your sentiment.
I was exclusively a Rebel player in 1.0 and loved the faction. I stayed away from a lot of the super broken 1.0 Rebel stuff simply because I didn't find them fun.
My experience in 2.0 has shown that I need to fly the big tanky damage sponge rebel lists to even stand a chance. Jousting and face-tanking with a mob of ships has never been my preferred playstyle and I've had to play Imperials in order to scratch the arc dodging itch.
I can see myself becoming a 'Resistance Main' as on paper they seem to suit my preferred play style a little better, and nothing in the Rebel roster really gels with me right now. Time will tell on that front though. That is not to say Rebels don't have a few decent options competitively either. In my eyes, generics are the greatest strength for the Rebels right now, and there are a few solid options if you like the Phalanx play style.
A single support based unique pilot helping generics is what has worked best for me in the last 2 months of playing Rebels in 2.0. X-wings and Y-wings are solid chassis' and are cheap enough to get a decent sized squad. Even B-wings have been ok as long as you keep them dirt cheap. Biggs is very strong for Rebels again as many are finding out. The U-wing pilots (even Bodhi) are all worth a try. Esege Tuketu has worked well, and so has Dutch.
Rebels have a few lone wolves that work, a la Wedge, Luke, Norra and Sabine, which will become even better once the rest of the faction is re-balanced. Options for pairings with these ships is where I personally fail to see anything of note right now, but that's not to say they don't exist. I just haven't found a combo I like yet.
I'd say if you have another faction to play maybe step away from the Rebels for a little while and reset yourself. If not, try and play some battering ram squads with some generics and see how you fair. My only other advice is keep it simple, and try a U-wing, they're actually quite good now.
