And here I thought my problem with leveling was that it took too damn long. Silly me. I also thought the biggest reason I quit on and off in Cata was because they pulled 5-mans out from under my feet to cater to a bunch of people whining about how people aren't wiping in small group content (the horror). My bad. Thanks for telling me how things really are, OP.
That being said, they gambled on posts like yours in Cataclysm and it blew up in their faces. Even today Blizz devs admit that it was a mistake and that any hard content will be optional for those who want it to go tackle it, not forced on the community at large.
