I don't think so - it's more like an admission that the MoP leveling experience is fun once or twice, but thereafter falls headlong over a cliff without a parachute.
You could say that about pretty much every expansion though. The best thing about Cata when it came to levelling as far as I'm concerned wasn't that having flight made things faster, but that it made it viable for me to take gathering alts and level toons just collecting the things I needed to make stuff for my main/to sell. That let me spread out the number of times I had to do the content and made it far more managable.
Except for Deepholm. Deepholm, while fun the first time or two, 8 times later can now go die in a fire. Really guys, between the Frost Giants in Northrend, the Elementals in Deepholm, and the Golden Lotus in Pandaria, can we please, please
, stop doing "mandatory to get x" zone/quest chains? For folks that do a lot of alts, they become tedious in short order.
PS: Experience doesn't really do much for me but, at this point in the game, can we strip Rep Requirements off of 5.0/5.1 faction gear? For folks trying to catch up, and those that hate dailies period, this would be most welcome. Right now I have friends that aren't playing 'cause they look how they've raised 3K VP doing things they enjoy, but can't spend any of it since every piece of VP gear is gated behind a daily faction save for 5.2 stuff from Shadow Pan Assault they can only get if they get high enough ilvl to get into the newest LFR.
There's a pretty obvious catch 22 there outside of extreme LFR grinding.
