I understand that, but without changing the core system, the new content will suffer from the same ailments the current content suffers from. Static rolls, repetitive drops, guns that don't make much difference in PVE, and therefore, PVE is more of a tedious, repetitive experience that lacks replayability. DLC will temporarily solve those issues by infusing the game with new loot, but the new loot won't be any better than the old loot - just different. It has to be that way to preserve the current PVP system. So that may be enough to keep you and your group playing, but for many others, it'll just be the same old crap, different day. Again, the DLC's will effectively be bandaids to large problems with the core design of the game - that can't be addressed without a major overhaul.
