I have been playing some games recently with the 2010 Wolfpack list, and I have found it exceedingly difficult to win with the pitiful number of reliable launch bays they can field. Similarly, the rogue trader fleet has barely any launch access either, and while it may go against the fluff for Wolfpacks or Rogue Traders to sport carriers, attack craft are such a major part of the metagame that the lists become practically unplayable against balanced lists from any of the major races.
While they are obviously meant to be gimmicky campaign races rather than legitimate fleets, is there any realistic way to compensate for the crushing lack of launch bays and create at least a semi-viable list?
