Pyro -> Any class with range (all except spies), open areas, sentry guns. Soldier -> No real nemesis. Scout -> Cramped areas, low ceilings, sentry guns. Engineers -> Good spies, snipers. Spies -> Spy checking, cramped areas, random pyros. Medic -> Any class with range (all except spies), sentry guns. Demoman -> No real nemesis. Heavy -> Scouts in open areas, classes with long range (sniper especially), spies. Sniper -> Anything at close range. --- This post is possibly/obviously sarcasm.

I dissagree with this one, the Pryo has decent health, and a fair midrange shotgun, so he's still fairly potent at mid range. so even midrange people don't own him.
Demoman -> No real nemesis.
I also have to disagree with this one. I said "spy" because often times a Demo is looking at his ambush waiting for someone to walk thru, thus allowing a spy to sneak up with a solid bet the Demo will be standing still. And unless the Demo is really really good, if you break thru his perimiter and get up close, he's in a panic. A direct hit or early det. can kill you up close, but many Demos panic if you storm them... if they switch to the bottle and your a class meant to get mid-to-close, you've most likely got'm. Long story short. If you get up in a demo's grill, you can ussually get him.
