Oh, that Iron Banner armor looks cool. How can I get some? Well, you can get real lucky and get it quickly. You could also spend a butt load of time playing and get it. Oh, P.S, there is a possibility that you can play the crud out of iron banner and still not get the armor before the event ends. So yeah, we're basically just offering you a chance to get that cool armor, not guaranteeing you can get it. you see, you really have no control over it. That's awesome! Thanks Bungie!
