They just stand there shooting at each other. They don’t actually do anything. They may as well just be a part of the scenery. You could drop them into a blazing, metal melting furnace, and no one would even notice they were gone. I’m not talking about the soldier-crit-shot reformists populating the steam forums, or the anonymous clan stacking apologists from OCAU or Whirlpool.
I’m talking about the god damn weighted companion snipers.

Circular Reasoning
You know who I mean. Those guys that hang out on 2fort (but can be found in most places). They each camp out a sliver of the balcony on either side of the map, nervously edging out to expose the same sliver of balcony on the opposite side, and try to take out the opposing sniper. And the opposing sniper’s only task - to nervously edge out and take a pot shot at them. And repeat ad-infinitum.
I’m sure some of these guys are talented Counter-Strike players. But that crap doesn’t fly in Team Fortress 2. Its useless at best, and a drag to the entire team at worst. If you’ve got 2 or 3 guys just standing there shooting, that’s 2 or 3 guys that aren’t helping you win.
Yeah fine, you can argue that they are controlling territory or helping with defense. I call BS. They are so universally cowardly that they can barely handle exposing themselves enough for a quick shot at the other sniper nest, let alone taking a look at what is going on below. They are dead to me. A waste of space.
And then you could argue that the snipers help the attackers by neutralizing the opposing sniper who would otherwise make life hard for your team. WHICH IS STUPID BECAUSE ALL THEY ARE DOING IS FIRING BACK AT THE FIRST SET OF SNIPERS WHO ARE FIRING BACK AT THEM! The circular logic fallacies of the whole thing makes my head hurt. I’ll leave chicken/egg debates to the intelligent design crowd setting science curriculum in our schools, but I’d hope TF2 players had a bit more common sense than that.
If you want to control snipers on the balcony, just lob a few stickies up there. Its amazing how quiet the whole deck gets once the snipers think they might get a scratch on their fresh nail polish.
The Aussie Battler Image
The characters in Team Fortress 2 are a bunch of shallow stereotypes, and I love them for that. They are hilarious. The sniper is no exception. He’s the type of solitary, isolated Aussie outdoorsman who spends weeks camped somewhere in the outback stalking a kangaroo or a dingo or something. He’s the guy made famous by Crocodile Dundee and the late Steve Irwin. Unfortunately, a few too many recent Counter Strike migrants have taken that to heart and embraced that proud ideal of standing around for HOURS not doing much. Croc dundee spent weeks in the outback because it is big and it is not filled with anything particularly interesting apart from flies, sand, and an occasional lost American tourist in a bathing suit. It takes a long time to do anything. Even going to the local pub for a beer is a week long expedition. 2fort has a slightly higher target turnover rate.
Just you know, hurry it up a bit huh?
(Hint - most Australians are actually much like anyone else in the world, except with a twangy accent that you get used to after a while. No, they don’t ride kangaroos to get to school here. Yes, they do drink a lot of beer. No, Australia doesn’t want Russell Crowe back)
The Good Snipers
I’m not ragging on snipers in general here. There are some great snipers out there, as OSI showed us the other week. A good sniper will pick a good spot to help the team and make life easier for the attackers and/or defenders, and will generally avoid the stupid “I shoot, you shoot” sniper duels, because they know they are ultimately unproductive. If you watch great snipers they are constantly moving explicitly not to get into those situations.
I’m not a good sniper (I’m just not patient enough, and my aim sucks - pyro was invented for uncos like me), but I do appreciate the good ones when they are on my team. The weighted companion snipers though… well hopefully they get kicked cause the server thought they were inactive (or dead), after not moving for 5 minutes.
