When the Interdictor was first spoiled I was not impressed at all. A 90 point ship, 100+ with basic upgrades, that shoots 3 blues and 1 red from each ark? Err, situational I suppose.
What bugged me most was the seeming inability of the ship to fit in any "good" build because of its high cost, low damage and low squadron related potential. Having won a couple games in a row with my buddy, I decided to play a more relaxed game and test the interdictor in a fun build (list here: http://armadawarlords.hivelabs.solutions/view_list.php?token=43635&key=b2a95595e077c70b453cc7c7e00add83).
I was really pleased with the overall feel of the ship: electronic disturbance in the form of speed manipulation is quite awesome, and at the end of the game it even saved the vsd flagship from certain death by repairing its shields (only later I figured out the healing potential of PE + yularen combo, gotta try that as well).
Anyway, since that game I've been trying to build an interdictor friendly list, not even necessarily centered on speed manipulation, but haven't really succeded: I can't seem to design a fleet that includes and interdictor where, on paper, another ship wouldn't be better.
What I'm trying to figure out is how the community perceives the interdictor, what roles can it fill and, most of all, what kind of fleets are you guys playing with him.
