Its called the 'Overlord' battlecruiser, and it doesnt suck.... its just overpriced for what it offers. Personally, i dont see anything wrong with the Tyrant (with the upgrade) because you have a stg 10 WB broadside at 45cm. I wouldnt mind paying the extra 10 points for the extra range. People say "Well, after 30cm, you have the right column shift, which makes it essentially useless" But i would rather an 'essentially useless' gun at 45cm, than a gun that cant even go that far, and so is "entirely useless". which is better? a weak (even if it is unlikey)shot @ 45cm, or nothing at all @45cm? remember, if your range is only 30cm, it counts as a big fat 0 @45cm.
And most people will find that that increase in range will help out alot in battles, i find it frustrating when my ship is only 2cm out of range with its 30cm range guns. If i had the extra range with a Tyrant, i would have at least had an unlikely shot at the enemy.
Back to the Overlord. Its a support gunship, your not supposed to send it in with flying broadsides at close range. thats the job of the dominator and gothic and lunar. its supposed to sit just out of range of the enemy guns and take pot-shots at them. People mistake its '4 gun platforms' on its side for use as a dominator. Its not. It sits back, and snipes. Thats why it has such a bad opinion in the BFG community. I for one dont mind the ship, although it is slightly overpriced for what it does, its still a stg 8 @60cm, which is double the range of all the other cruisers. Its doesnt suck, its just theres a better battlecruiser out there.
and that is the Armageddon class!!! it combines good firepower with range, its a mix of the overlord and the lunar. Its got 45cm guns (and lances). Think about it like this, 1 lance = 3 WB, so stg 2 lances is stg 6 WB. the armageddon has stg 6 WB in one broadside, and stg 4 lances (inc. dorsals) so all up thats stg 18 WB @ 45cm (using the special rule thingy) which is pretty awesome! and its the cheapest out of all the battlecruisers. Thats why i feild 2 of them
