I can understand shortening the ARR quests...I've personally seen people I've introduced to the game quit or lose interest before it even gets good due to the pacing. I've heard that they'll be shortening it at some point in 5.1.
But this...
You're playing the wrong game if you feel this way. It's an MMO...you can pretty much expect to play with others. Waiting until the "endgame" to do multiplayer content would be a terrible idea.
