I always wreck with it. While it's immensely fun for me, I understand that in the right hands you are incredibly difficult to stop. You permanently oneshot everybody, you're faster than any Guardians on foot, you have great splatter potential, your shots are insanely accurate from long range, you have very rapid fire, and you can cap territories while still in the interceptor. To kill it you either need a Super (which a pilot can avoid by simply moving backwards and shooting you), a rocket (again, just keep distance), or a sniper (again, just keep moving). It's incredibly easy for a smart Interceptor Pilot to stay alive.
It's definitely overpowered. I would have been fine either way- with or without a nerf. But as an Interceptor user myself, I can safely say I understand how powerful it really was.
