Nah, its definitely faster to get from 1-90 than it was to get to 1-60. I used to level race all the time on fresh servers in Vanilla and the fastest we got it down to pre-xp nerf was just under 5 days played. You can get to 90 now in about 2 days played, without any xp boosts besides the guild xp bonus...which is essentially universal these days.Assuming you aren't using any of the catchup mechanics they've implemented since vanilla, then the only reason it would be faster is because they streamlined the quest hubs and you never run out of level appropriate quests. The amount of time it takes to go from 1-90 is within 5-10 hours of the amount of time it took to go 1-60 in vanilla.
As for the video, I agree wholeheartedly that this is one of the biggest factors to WoW's demise is the accessibility of content. There's no "wow" (excuse the pun) factor anymore that feeds into the whole psychology of the fantasy genre to begin with. There are no deep, dark, dangerous dungeons anymore. LFR is just the newst iteration of the problem that began when they started Scarlet-Monestarying (SM'ing) all the 5mans begining in TBC. It all goes back to my immersion-is-king theory and WoW is failing pretty hard at that when it comes to the content other than the outdoor leveling zones.
