You should probably watch this Team Covenant interview with the new team working on X-wing. They address a lot of player concerns that I see weekly on the forums, including:
Interceptors vs. Turreted ships, and turret ships in general
TIE Advanced
Power Creep
Blocking
As well as lots of other tidbits on the way things are going, including the design philosophy behind S&V. This is a must-watch for anyone who spends half as much time as I do trawling the forums.
