How MMO Quests Get it All Wrong

My personal feelings on the state of PvE leveling in MMORPG may best be summed up by an article I found while in the middle of writing the one I’m about to link. In his article titled PvE Leveling is a Waste of Time, The MMO Bro bemoans the quest grind as an unnecessary time-sink spent of low-quality content placed in front the players before they can access ‘the real game’, an opinion that’s grown increasingly popular over the years.
My article isn’t about how miserable the standard quest grind is, but rather the reason it’s bad to begin with. With all of the resources recent MMOs have devoted towards improving the questing experience, you’d think they would have gotten better by now, right? Not when there’s a fundamental part of the way modern MMOs are designed holding them back.
