Server Filter needs to be added!
I'm getting more and more frustrated by the lack of control and availability there is for finding Vanilla servers. Yeah, yeah, some people like XPM servers or other modded servers, but what ever happened to the real game? You can search for Official servers, but half the time, you simply get redirected to a third party server or some rented server with mods out the ear. I don't care about aesthetic mods like new characters, weapons, sounds, whatever. I am sick to the teeth of coming on and expecting to play a nice competetive game of L4D2 and finding nothing but "for whatever awful effect, type !xpm" popping up every time i join.
Valve, for goodness sake, help the core gamers with a filter so we don't wind up in those modded snoozers!
