Yeah not sure why people care if they are geared or not, heck they don't even have to do dailies on them if they don't feel like it (gasp). Hell they could just stop playing them when they reach 90 and start leveling up another 11 if that's what they enjoy, what's it to you how other people enjoy the game.
Grats to the OP, that's a lot of work and something I wish I could do but only managed 8 85s by the end of cata (with 2 druids).
As for MOP, I'm working on my 3rd toon, definitely skipping some of the quests that I didn't enjoy the first time. Adding a little PVP and a few more dungeon runs to mix it up as well. Going to have to take a break from leveling after this one though as I've gotten a little tired of it (I'm sure I'll get the urge again down the road and level some of the others).
