It wouldn't be so bad if the stuff at level 50 was somehow still relevant in a way that got people together in the same place and communicating with one another. The one consistent complaint I've always had about FFXIV:ARR is that it is built around content that doesn't require social interaction and the content that does was slapped in as an after thought. Even in dungeons there should be choices that require people to ask one another what they want to do next. After all, if the game is designed to make social interaction unnecessary why bother making an MMORPG at all? Multiplayer minus the social factor is a lobby game.
