I came back to wow and boxing after a 2 year break. Both servers (pvp) i had toons on had a mass exodus of the opposing faction, making the ratio worse than 10-to1. Previously, both were among the top 10 in population when i quit and their balance was between 50-50 and 40-60.

I started over again using RAF and research the server populations on warcraftrealms.com or someplace like that. Anyway, I'm a lot happier on a 50-50 medium population pvp server. I have only played on pvp servers. Being on te losing end of a 10-1 ratio while leveling is a nightmare and will be even worse now with world flight. Being on the high end of the ratio means you'll rarely see people your level to kill in world pvp. Anothrr thing to keep in mind is that a low pop server's ratio can be changed with relatively few people getting fed up and leaving or quitting.

Excuse typos. Ipad keyboard.
