Hi,
First i wanna tell you that i'm not a scammer(Yeah right, like someone believes that) sure you have a good reason to not trust anyone that just created a account,
but i have a US key i can't use because i don't have the US version of Mists of pandaria so i cannot use the beta key, i won it in a giveaway, but it didn't say anything about that it was for US.
So i want to trade my US key for a EU key, and if i can do something to make you trust me, then please tell :-)
Also i prefer someone that is trusted, i just want to be on the secure side, i know i'm not fully secured even if it is a trusted but better trusted than a not trusted one
Kind regards.
