To be fair, if you like questing and I mean you legitimately REALLY LIKE leveling and questing, nobody is FORCING you to use the feature. When you make a character, how fast you're going to level them is related to what you're going to use it for, raiding, farming, just for teh lulz?
The only complaint I have about it is I'll never want to go into LFR again. I don't care what special set up they have for it, the class familiarity will not be there after 10 levels. It feels like it'll make LFR just so much worse with people jumping in with characters they've barely played for 1-2 weeks.
