It sure says something about your game when people would rather sit outside a cave and shoot the same two enemies for an hour rather than play a mission. There are just so many counter-intuitive decisions made with absolutely no reasonable justification. Require online connections so you can see other players, but interact with them in no meaningful way. Waste precious engrams on items for classes you aren't playing, yet allow no trading or gifting. Make purple engrams extremely rare, yet make a legendary yield unlikely. A blending of genres is supposed to take the best of other genres. You can blame the community for not emphasizing Vanguard/Crucible/Faction reputation, but I'd put the responsibility on Bungie for not properly incentivizing it.
