Power leveling. No quick way to do it.

Botting: Honorbuddy, download a grinding profile. Not only will you get a shit ton of motes for level 90.. but also you get plenty of loot. I would not recommend using the PvP function as 1 it is pretty slow and 2.. there are so many people bg botting at the moment its very clear whose botting because they all follow the same path in bgs. I have a feeling a big banwave is coming. Mob grinding seems much safer atm.

Legit: Battle Grounds, while not as fast its much more amusing if your playing them yourself as 8/10 people are botting in the 85-89 bracket.

I would also suggest to buy / download Honorbuddy and then download all the question profiles from 85-90. I was really impressed the first time I used it. And it also switches the profiles automatically after each zone and level.
