I think this past DLC is a good example of what would happen if we could level up year 1 legendaries to year 2. We'll go back to playing a looting game that everyone hates. In all honesty, besides trials weapons, what legendaries from HoW has everyone been using? Like 3 at most. Her benevolence, Ill will and the fulcrum are the only weapons I ever hear about on the forums. Seriously if we could upgrade all our stuff for the next expansion, we'd just be as disappointed as we were with this expansion.
