If you want to try to become Realm 1st! 85 can you tell the rest of us why?
Because I, personally think that is a one unhealthy step to take as you obviously take the game way too serious to just play 24\7 to get a stamp on postcard so to speak of.
I hardly think anyone beside those that think of this game as their life will admire you for getting Realm 1st! 85.
So it's safe to say I guess that those who get this achievement think World of Warcraft is their life, that's bit sad achievement to get. My opinion.
