Yea I was worried about that - as a spectator it looked cool, as a player, I thought "so my average life-expectancy will be what, 2.5 seconds average???"
Something tells me this maaaay not be the case, even for the ol' glass-cannon Tie Fighters from the days of old. Initially there may be some good'ol' Battlefield spawn and die feel to it, but I think if you have a patient approach, you may be able to survive before getting into the thick of things.
The problem remains though - that's easy to do on flat terrain, right? Stick with your buddies, pick your engagements - how on earth do you do that in free-form space??
