Every loot based game I've played has always had something better to strive for as a goal. The only time this aspect ended was when you neared the actual end of the game. As the challenges got harder the gear needed to overcome them got better. I've never played a game where the best the game had to offer was attained at the very beginning and the rest of game became smooth sailing to the finish. The BIGGEST mistake made by Bungie was to allow items from the original release to progress to the point it was capable of EASILY dispatching targets/challenges in the DLCs. Their second large scale gaff was removing weapon/gear as possible rewards. IMO, if I played original game storyline/activites then the loot/reward system should be weighted in such a manner that I am more likely to gain items from that era. The same would apply when playing TDB or HoW specific events. Doing so I think would satisfy the collector in me. But still I'd know that such gear would become increasingly ineffective as I progressed to new content but would always be quite playable in PVP.
