it's easier to get exalted since blizz change the rep gain rate for a lot of the quests when TBC came out. and i think if it's the same as alliance, it would be possible to still get rep gain from the low level quests. the only horde/alliance faction that had rep penalty at lower levels were the draenei and blood elf. but need someone else to confirm this.

It's there USD15 a month. They can do whatever they like.
