I don't know if it's stupidity, or some disillusion borne out of a bizarre infatuation with Bungie, but how is it not obvious that these rotating buffs/nerfs are a lazy developers way of artificially padding content. How many of you lemmings went out looking for that new and great pulse rifle, playing the same repetitive shit over and over again with newfound enthusiasm, while abandoning your favorite auto or HC in the hunt(the two weapon classes most of us used). Bungie even admitted this. A competent developer relies on content cycles, releasing a new tier of weapons and armer along with more playable content.
