If exotics were truly rare, they'd be great. But if they were truly rare, it would suck to only be able to use one at a time. I'd love to see actual rare, OP exotics that you can equip as you see fit. It'd make it cool to see, even in pvp. Imagine that truly 1/1,000,000 weapon. Even if it killed me in pvp, I'd be happy to say I saw one. This is basically what the hawkmoon once was.
