The BH BC is all about positioning if you enter a fight the wrong way you'll leaving it in more than one piece. It's got bad turning and it's pretty large from all sides.....
the lib forward gun is good for wide/fat targets you have to almost ram something to hit it.
The huntress.....Oh god. I have an easier time flying a BH BC through O-5 than the huntress in Ommicron delta.....
I have a Brit Dessi and it is ok. The front guns have a very limited firing arch. The concentration of fire forward is fair, to the rest of the sides it is pretty poor. Manuverability is pretty good and armor is good.
I have it set up as a cap killer with a mortar to the front and to the back. The rest of the turrets are Basic ones so I can fire while charging the energy back for the mortar.I have one missile turret on the 360 degree point on top to stave off bombers.
I don't really use this ship for PVP much, it is mosty there to RP a Brit patrol. I have found that it works pretty good just because it can manuver pretty well and let you keep the front guns on the target by strafing.
