I've definitely had similar feelings in Half Life 2: Deathmatch. I'm particularly fond of "low grav high kill" servers due to the fast pace (the low gravity enables a lot more movement around the map, and the "high kill" - i.e. weapons buffed / health nerfed such that getting hit by anything results in instant death or close to it - ups the stakes). Unfortunately, such servers often feature "sniper" maps, wherein players "in the know" will scramble to find the "hidey holes" and repeatedly slaughter any of us unfortunate schmucks.

It got to the point that on such servers I'd protest by refusing to use guns at all and used a crowbar and grenades exclusively. Not sure if anyone really took note of what I was protesting against, but it sure got me on top of some monthly crowbar kill leaderboards :)
