I come back every once and while to CoD4 but quit almost instantly because although I've filtered out "hardcore" servers (reduced health), which I don't enjoy playing on at all, every server in the masterserver seems to be one. I don't know how they're bypassing the filter, I guess not by setting the server config option but modding the health or something, but it's annoying and makes me stop playing the game. It would be great if servers that use reduced health would be filterable again through that "hardcore" filter in the client.
