According to a few of the Video Docs I've watched they expressly said that their whole goal was to make sure everyone wasn't waltzing around with the same exotic weapons and armors equipped. That no one you approach will ever be the same. So that leads me to believe there will be various exotics OR variations of each exotic....depending on how they handle drops/loot etc. If Boss A Drops Closing Time at ??% then every Hunter at some point will camp that boss until they get one. If the stats on that drop are randomized; plus add in leveling it up and customizations....then I suppose it's possible that every closing time could indeed be different and never identical. I look forward to seeing how they back up this claim.

Right!? I mean they're exotics for a reason for I hope they live up to its hype. But other than so that blood stain barrel and the bayonet attachment though!
