I have a Kagutsuchi, beautiful ships as far as looks are concerned. In Combat it's a ship that takes a lot of practice for it to be any good. That forward Cannon is essentially a SNAC with faster projectile speed and faster RoF but it's by no means easy to aim. If are willing, you can use a wax pencil ot a little piece of a post-it on the middle of your screen to use as a reticle, it helps. In a fight against caps you'll only really use that forward cannon and maybe a Light Mortar (this Cruiser has enough power to fire both simultaneously but only once) so concentrate on antifighter weapons for the rest of the turrets and always be close enough to a route of escape.
To be honest, it's only good for its looks which is quite pleasing.
Performance wise, it's pretty terrible. If you do buy one though, make it into an anti fighter/bomber cruiser since you can't go head to head with ships of equivalent class and you're a big target.
Well, seems i didn't said anything new. So i'll add some more sentences to make it look not like a +1 ;]
I had one, for some time. Fought few times. That cruiser is really really really hard to win something with in Kusari. If you can see I highlighted "In Kusari" part of last sentence. Yes, That cruiser is out of place in the land were ships are made of chair and some wings attached to it so you'll never see a good target for it. Hatchet is epic and Kag is on the other end - useless. So on all equals you'll die to it. Blood dragons just don't need such ship to begin with, there is completely no use for it.
