I flew the Collector for a bit. Good for RP purposes but in PVP I got a couple PVP whores in Eagles mad at me because I couldn't get them in my sights and had to force a no-win. For the life of me I simply could not maneuver to get even the slightest advantage.
It doesn't turn, it doesn't have the guns, it doesn't even have the plant to shoot the guns it has. It has good armor, but it literally turns like a SHF. You might as well get a SHF and have more armor, more guns and a bigger plant.
But as a smuggler escort it's great simply because it has a 360 degree firing arc on its CD slot.
