The data is not really that reliable, I found servers who theorically had 0 alliances and 0 hordes due to lack of updates, and several others who had no updates from one faction and hence the server would appear imbalanced.
Also, generally speaking, there's more reliable data about RP server and, to a lesser extent, PVE servers.
All the data is based on lvl 80 characters *ONLY*.
I mainly made it for my use, trying to find a decent server myself, but I figured somebody around here might be interested in it too
Also, I apologize for the lack of consistency in formatting and possible errors (entering the data manually means I must have made some errors).
The servers with the red name are the ones which lack sufficient data to be reliable according to WarcraftRealms.
