It is the board control ship to beat. Various stress and ion ordnances available, stress bot or R7, spend a few points more and get all of that plus dutch for a great support ability as well. Soon we will be adding bombs to the mix. why take a B with ion when you can take a Y with 360 ion?
I think, as an ECM / Movement control ship, it is the best thing out there. also, it's cheap and tough.
Now I just need to practice so I can ion people into my own prox mines....
