Eu server but which one?

[Zee824]

Hi everyone ,
I need to transfer server to a medium or high population server in the eu and i wanted to know which server you would recommend? I want to transfer for progression i am on a low population server at the moment and the "top" guilds only want people they know personally (I'm being completely serious)and the "casual" guilds are still doing T11 normals. I would prefer to be on the horde side as I have been alliance for far to long and want to experience the other side. However, all suggestions are welcome.
Thanks in advance.

Sort for your preferred language and check for the population row and ally to horde ratio, depending on your favored faction.
