Energy weapons have one major advantage over any ballistic guns: infinite ammo. Vanguard is a long range heavy fighter. I always assume it might take some time before I could refuel and rearm this ship. And there is nothing worse than running out of ammo in the middle of the dangerous universe.To the original question, though I keep hearing the ATSV melts shields and then the ship comes down, the times to kill seem very long to me. Way past ten seconds minimum.
I think ballistics have got to be killing much faster.
