I would love to have in destiny every exotic and legendary weapons have random elemental burn. Like how gearbox did in Borderlands where every weapon came in different element. Can you imagine the grind that people would do to get an Gjallarhorn in every element or even been able to have a hawkmoon in with a burn. Sure that this elemental primary's would be very rare but it can make the hunt for exotics more interesting. I would love to hear what you think about it and if you have any new awesome idea that you would love to see in destiny.
