Zoom made PvP easy to learn, everyone has mastered the art of holding sideways and holding down the trigger while occasionally turning to a different side or (gasp!) he slammed reverse?! musta taken along time to develop those skillz!
But yeah, the two reasons I loved disco was that the interaction environment was always subject to change. And TWO: The sky was the limit to bettering yourself in PvP (this is still the fact with snubs, but no longer with anything with zoom).
