I'm working on getting 2 of each to 90; one of each class and faction. I haven't been able to update my sig but a few of my 85's are 86+ now. With fully rested xp; it really doesn't take a lot of time to level some toons. Other then getting bored of doing the same quests on multiple characters I enjoy leveling (and when I get bored I just log on a 90 and do some pvp/dailies/LFR) to break up the monotony. I don't have the time nor desire to raid "for real" so leveling is where the fun has been at for me! I don't know why they stopped at the whole 5 90's ach. They have to know that there are people who would rather level toons and have some fun then to raid the same content over and over.
