This may be a no brainer but I think I have discovered that: more ships beats upgrades.
What I mean is for the past few weeks I've been building alot of different rebel lists for abunch of different match ups but was always stopped by a lack of cards, mostly imp things like the advanced sensors and such. Frustrated at the idea that I would have to get a few 30 dollar imp shuttles I threw upgrades out the window and built a 5 man rebel swarm. To much success!
I found that having more ships (mostly of the same pilot level) was far more fun to play with and having been winning alot more often. Now I am fumbling around with the ships to use and apart from a 1 or 2 point upgrade I can't think of single upgrade (or upgrades) that would force me to lower my ship count, I feel that more bodies just help much more then upgrades. Also I feel it has helped me start flying my ships better since I get to do a lot more flying and know my dials better.
Does this sound true to anyone else? Maybe just some good fortune has come my way and I've flown it to victory?
