Just because they're adding new things doesn't mean everything before it has to be irrelevant, that's just stupid. I'd be happy to use new guns and armor if I like them, but lots of new stuff they've added looks worse than the old stuff, and if that trend continues you're damn right I'll want to keep using at least some of the old stuff (most notably armor, almost all Warlock armor in this game is absolutely hideous and the best looking stuff in the game was the original vendor gear from before the first DLC, everything since has been progressively worse and forcing people to abandon what they like is no proper way to move a game forward).
