There are such servers. While still new (2 months old), we strive for balanced PvP that isn't measured by the size of a players wallet. Please feel free to check out Battle for Dwater
B4DW 
. We have a strong euro pvp player base if that might fit your play better. It's not constant PvP, but as mentioned before we are steadily growing. Talk to some of our regulars in chatbox. They are open and can give you a good assessment of
B4DW's strengths and weaknesses.
