Challenge mode... Run the raid, and kill one specific boss in one specific way... When I first read what this was, I thought that surely it was a joke... This is what Bungie has been hyping up? Give me a break... At this point, I'm not sure who is more embarrassing... Bungie, for presenting a minor tweak to a three month old raid as "new content" and an "all new challenge mode", or the people actually think that the got new content, and seem to be crazy excited about running a raid that is 95% identical to what they've been running over and over again for months so they can get three items that do absolutely nothing in game...
