I think this xpac is not alt friendly because of the reputations, and dailies grind. However, I've found leveling a bit more enjoyable doing more dungeons and pvp instead of questing. I know some people enjoy the questing part and I do too, BUT I found that if I mix things up a bit more by doing other things that give xp, I find myself enjoying the game alot more now.
Just do some quests and sit in queue for dungeons or bgs while questing. Its a much more enjoyable experience trust me.
Plus you have the added bonus of some decent ilvl gear at 90 if you can honor and justice point cap.
