If I am looking at the information correctly than one of the best in that category is Zul'jin. But than, I am not sure I am looking at the right info, it says that the population of horde is 51% to the alliance's 49%.
My question though is that Zul'jin had a transfer to the new pvp server and are the numbers for the population on Zul'jin the correct numbers? Or is it before the transfer?
Also, if anyone knows of another server that is strongly horde than that would help me as well. Or tell me a better way to look at the provided info and find another server myself
