Is it possible they overlooked that the commendation, that you can get when you're revered, that gives you 100% additional rep, also applies to your first character? So as soon as you hit revered you get double the rep and revered to exalted, for me, felt faster than honored to revered. Yesterday I was able to make the jump from 10000 to 17000, because I had the Purge of Dalaran quests, then I did the normal dailies, and then I did the Monkey King quests, and today I made it from 17000 to exalted.
Before revered it felt like Taylor had a new quest for me about every 2-3 days. As soon as I hit revered it was like every 1-2 days, and once even twice a day. My Horde character is still at 6585/21000, and I only missed one day of dailies with him.
To me it looks like they planned the whole pacing of the quests without the 100% increase in mind.
