Its been a while since I've looked at a ship class with no experience or strong expectations on how to fit it. I pretty much ignored interdictors since I could never find myself prioritizing Destroyers V over another skill until very recently, especially with the Heavy Interdictor in my arsenal.
So now that I can actually fly the Flycatcher, I found myself at a loss for fits beyond the unique-to-class Interdiction Sphere Launcher. For the uninitiated, while Tech I destroyers are designed for dealing with frigate classed hulls with lots of small weapons with bonuses to tracking, the Interdictor class is designed primarily for the ability to launcher warp disruption bubbles with any combat ability secondary. (That may not have been the devs' intent, but it is certainly the result.)
So I checked some corp mate ship fittings and played around and came up with two setups for slightly different purposes.
The first setup has a single goal: bubble while surviving. To this end we have the double-bubble setup with two interdiction sphere launchers so that you can drop a bubble and jump through a gate to bubble the other side (or alternatively try to cover a large region gate). The cloak gives some tactical flexibility and since this ship is weaponless the cloak's negative impact on targeting speed is ignorable. The disruptor is for those occasions where the bubble is overkill and perhaps detrimental to your own fleet.
The second setup is more combat oriented for small gang roaming, with some anti-frigate DPS and higher top speed and agility, along with a web for pesky fast moving targets.
Opinions / comments are welcome as I'm not very experienced with this class and would love to hear what people do with them.
Footnote: I can also fly the Gallente Eris interdictor but taking a look at its split weapon system, split weapon bonuses, and anemically low CPU made me realize that only the desperate would fly that ship. Even with a Co-Processor II I was unable to fit a MWD, cloak, and two interdiction sphere launchers. Going with a combat fit looked a bit better but its still lacklustre and might as well go with the flycatcher. If anyone has a good Eris fit, please share.
