Such as heroic dungeons. There have always been two progression paths. In the past casual players spent months running heroics and/or attunements and/or rep grinds. In Cataclysm all of that content was repurposed as a means to get players to raids faster. The (flawed) assumption was that all casuals wanted to raid and would do so if only they could get to the raid in a reasonable amount of time. These days you ding 90, clear the "heroic" versions of the same dungeons you probably ran while levelling, and call it a game by the end of the month because the only activity to look forward to beyond that is LFR. But please go on thinking that this game is casual-friendly. It's anything but. The only thing you and I probably agree on is that LFR sucks.
