I would love that so much, it could reward nothing and I'd still play it. But I don't want the enemies to be easy either. No defense target, no objective, no modifiers, no reviving yourself, and nowhere to run. I want mostly gunplay, with the occasional ability. Thrall, Acolytes, Wizards, Knights, Ogres, and Shriekers. I want a lore accurate experience against a Hive army. An endless experience where survival isn't possible. The goal is to last as long as possible and kill as many Hive as possible, both contributing to a score that you can compare to your friends and clan members. This is such an easy, barebones idea that would take incredibly little effort to do. So obviously Bungie won't do it. But I can dream.
