It's worth noting that, at long range, a torpedo frigate actually puts out less dice from the side than a Nebulon. With EA and Ackbar, with a CF command, the Neb B can put out 5 red dice from it's side arc.
Granted, it doesn't have much ELSE going for it in that regard. No blue or black dice to speak off, only one shield to take return fire (and no redirect) but that's why you have B Wings to provide that close range firepower.
Of course, now you're talking about 100+ points for a Nebulon B and support squadrons...
Oh Nebulon, why are you so hard to include in a fleet?
you lost me
