In order to unlock Allied races on Alliance (I have only ever played Horde - don't have 110 Alliance character), is it required to get a character to lvl 110 on Alliance and then do all the requirements (exalted, quest chains etc.) OR you just need to get to lvl 110 on the Alliance and if you have unlocked the requirements for that allied race on the Horde side, you automatically get the quest chain for the allied race?
