Spend hours upon hours grinding it out, because shortly all of that grinding will mean nothing when the new weapons and armor are out to make room for the new (or see the weapons nerfed) . Then grind the hell out of those, just to see it happen again. Here's one guy hoping that "The Division" will be all it's cracked up to be so I can leave Destiny on the shelf. I'll be amazed if Destiny makes it 5 years, much less 10.
