Space Marine Navy

[fleetmaster]

The Current Design that Battlefleet Gothic uses for the Space Marine Cruiser, sucks in terms of armament. As a Space Marine Commander, I only have five ships to fight with. Granted, the Cobras/Hunters are my faves, especially effective in the multitude of Nebula Ambushes. Also, I was wondering if you people would ever do an online campaign, I kick my room-mates' butts all the time, too easy. However, I only use four ship types, preferring to rely on the Hunter-Cobras and the Battle Barge to be in the frontline and take on the heat. What I propose is to remove the weapons batteries (str 8) on the Cruiser, and instead put in Lances, (str 3: 8/3 = 2.67 and round up) with range 45cm instead of 30cm. I think it's a bit silly for a quick strike vessel, as Space Marine Vessels are, with a 90 degree turning radius to have starboard and port weapons, hence the Lances will have the front arc. Or it can be front/left/right, with that turning radius it doesn't really matter. Otherwise, Space Marine Fleetmasters that win, simply won't use the d**n ship, and go with a Hunter Sqaudron instead. Also, are there any rules for including two Cruisers if a Space Marine Chapter's using a Battle-Barge? If so, please let me know, cause I think I've been violating those, I just used the 1,000 point rule. Also, here's my navy, as it stands:
Battle Barge - The Obliterator (425) with Warmaster with re-roll (500 total)
Four "Death Cobra" Hunter Squadrons (480 total)
Alpha, Beta, Delta, Omega (4*3). 980 Total Points. I am also wondering if the Weapons Batteries on my Hunters could be upgraded to Lances, but their movement reduced to 30cm. Also, I don't see why the Gladius are the most common escorts, I enjoy the Hunters much more.
