Slowing down xp gain while lvling from 7x

[tomenajak111]

I heard some people talking about this but is it actually a thing on Icecrown? If yes, how can I do that? I am actually enjoying lvling and chilling in no mans areas sometimes alone and I wouldnt mind it to be slower...
Is Lordaeron the only option I have?

lol, so easy? this made me feel stupid now, I didnt know thats a thing :D
1 more thing, does this slow down everything aka reputation and skill lvling or just xp?

Just experience.
