Presumably it has more bomb/torpedo/missile slots than the Bomber.
Now, I don't know about you, but the Bomber already has more than enough such slots for me.
"Ah", I hear you say, "but this wave comes with the 'ordnance fix'n"
Maybe so, but that means one of two things:
• Ordnance is fixed enough so that the old ordnance-powered ships are now worth taking, but not overpowered, and this new ship is not worth taking as it includes a big overhead for all the ordnance it can carry
• This new ship is over-powered since they've fixed ordnance and this baby gets the most of it
Obviously it's also possible that FFG have balanced all of the bone perfectly, but we'll see.
Personally, I'd have liked to see the ordnance fix come with standard, non specialist ships that just happened to be able to take the odd ordnance, like X-Wings.
