Biggest problem with this entire idea is the fact that there is one key element that separates Destiny from other FPS-type games. That element is the "gotta catch em all" factor. Let's face it, most people don't run the raid because they think it's great fun. If they did then everyone wouldn't be trying to figure out ways to cheese. The real driving factor in playing this is the same reason that people used to play Pokemon games, item collecting and bragging rights. If they didn't replace the old standard quo (VoG items) with a new standard with expansions then they would lose that factor and the game itself would lose a large part of why people enjoy it. If VoG weapons where upgraded to be as good as Crota's, why bother trying to get Crotas and HoW in turn?
