In my opinion legendaries should be left behind, and players should be forced to adapt and find new weapons. But to make year one exotics obsolete would be too far. Exotics are supposedly the most powerful and unique weapons in the game and people get attached to certain guns. In the stream it seemed like only a certain few exotics are coming forward and the others are getting left behind. This isn't fair to the people who got very attached to the weapons that aren't coming forward. That would be a huge issue for a lot of people if that is the case. As for the rest of the stream the changes are fantastic. Just my 2 cents.
