This isn't the point. The difference between a Murder and a Hades is that the Hades costs 30 pts more, has 2L@60cmLFR and has stricter composition limitations. So adding 2L@60cmLFR for 30 pts and no other change is inaccurate.
Sorry, if I drop it in too harsh... but that's just crap.
Following that logic every ship with a restriction should get a price reduction.
...like Imperial Light Cruisers for expample.
...or Grand Cruisers and Battleships besides Battle Cruisers.
...not to forget this nasty limit on ships with a Nova Cannon.
How many ships in IN or Chaos fleets does that leave that are "priced right" in your eyes?
Those ship restrictions are not there as a punishment, but merely as a way to prevent a spam of "goodys".
