"One of the primary reasons I stopped playing was that I felt like so much of what made raiding interesting and fun was that elite end of the game where you have access to content that only a few people every get to see," Doug Thomas, Associate Professor at USC and co-author of A New Culture of Learning: Cultivating the Imagination for a World of Constant Change, said. "Systematically, I felt what Blizzard has done is taken their high-end game content and made it increasingly accessible to larger group of players."
"Even if you couldn't get the high-end Epics, you could get something that was pretty much equivalent through token systems. That kind of thing kind of eroded one of the core dynamics about what was fun about the game for me."
Translation: There are always more people who would rather wave their peens in other people's faces, rather than get better at using those peens privately.
Thus, if you remove the option to have the rarest, biggest, purplest pixellated peen, those peeners would then rather quit than continue.
