I believe this is the real reason we're hearing bungie's quote "Philosophy" non stop when ANYONE mentions this massive flaw. Im pretty sure they can't go back and build ingame LFG because its too late. Someone overlooked this completely, then went oh, whoops, we didn't build in a proper chat system or matchmaking for endgame...lets just keep repeating the same lines until the fans boys drown out the complaints. Its painfully obvious they would have to rebuild the UI mechanics from scratch in order to accommodate us Lone wolves, and who cares about lone wolves right? Takes quite the tunnel vision developers to overlook having NO chat system, and no UI based manual/auto matchmaking for end game. I guarantee had they stated their philosophy during the hype train, many a nerd would have cancelled their pre-order, including me. 10 year game? Not with this nonsense. If WARFRAME can do it...SO CAN YOU BUNGIE!
