I agree and disagree. I understand the need for progress, but it wasn't long ago I got my Fatebringer. I am not willing to give that up along with other guns without equal replacements. But even if Bungie releases an equivalent to Fatebringer and other guns... RNG. The issue is that I like the feel of certain guns, and obsoleting them will upset that. This isn't like a typical MMO where that lvl 30 sword feels exactly like the lvl 10 one. Edit: Also, just because other games' expansions work a certain way, it doesn't mean Destiny's must as well.
