If you hate grinding mobs as much as I do you probably despise the way we're supposed to get to exalted with the wod factions. Well I faction changed today after doing all the quests on my Alliance characters that awarded reputation with the Council of Exarchs, I was maybe 2000 points into exalted. Anyway the thing is, when you transfer from Alliance to Horde (or the other way around) the faction simply get converted to its Horde/Alliance counterpart (while the amount of reputation you've earned remains unchanged), allowing you to do all the quests that give you reputation again, making it really easy to get to exalted without ever having to grind.
So do all the quests on an Alliance character that reward reputation with the Council of Exarchs faction -> faction change to Horde -> you can now do all the Frostwolf Orcs quests and it's really easy to get exalted that way without having to grind mobs.
