Lightfall killed the power fantasy aspect of the game for me. The player guardian has slaughtered entire pantheons, I understand that some people wanted more of a challenge. But that's no excuse for a thrall taking three magazines just to get it in finisher range. At this point in destiny's life cycle, weaker enemies should flee from us like they flee from the witness. I remember a time when bullet sponge enemies were a bad thing that bungie worked to remove, now that's all they give us. It's kinda sad if you ask me, it's also the most artificial way to "boost difficulty".
