To start off, I very much enjoyed playing the beta and getting a first look at everything. I tried most of the factions, did some 1v1's and 2v2's with the A.I. and other players. So far, it looks like a fantastic expansion upon the first.
Besides the balancing issues, my friend and I believe that the health/shields of all ships is just a bit too low. It seems like ships die too fast. Not from troops dying, just ships exploding. We would like to see ships out there for a bit longer, even battleships seemed to be offed fairly quick.
