Most, if not all experienced Pyro players will choose the Degreaser over the default flamethrower any day, and you can't even use the Phlogistinator or Backburner for crits to try and burst down the Heavy. To make matters worse, it only counts the default flamethrower for the achievement. Not only do Heavies completely heavily outmatch the Pyro's damage output at close range, but they have absurd amounts of health, the Sandvich, and Medics to combat afterburn damage as well, means that you can't even rely on hit-and-run or posthumous kills. Makin' Bacon: Kill 50 Heavies with your flamethrower.There are career Pyros out there that still don't have this one. Pyromancer: Deal 1,000,000 points of fire damage as a Pyro.And you have to do this on Snakewater, a map almost nobody outside of competitive plays.

The Snakewater pack added 'Mutually Air-sured-destruction', where you and an enemy have to be rocket jumping, and both of you have to kill each other with a rocket while you're both rocket jumping.

'Out of the Park.' It doesn't just require you to get a kill with the Sandman's taunt, the longest in the game- no, you have to hope the enemy's ragdoll flies long enough and doesn't collide with anything to count the achievement.

It's gotten even more difficult with the Sandman being nerfed to only slow enemies instead of stopping them from moving entirely, meaning that the victim will have a chance to get out of the way. And the Sandman isn't exactly easy to aim in the first place. What this translates into is hoping to smack someone with a stunball (usually at long range, as the Sandman doesn't stun enemies up close) in the path of a buzzsaw, on train tracks, or in front of the Horseless Headless Horsemann and praying that they get killed by that hazard before the stun wears off.

'Foul Territory' requires a Scout to cause an environmental death by stunning someone with the Sandman.

This can literally take dozens of hours to do, and while dedicated Scout players will get it fairly soon, those not so good at playing the Fragile Speedster will find themselves in a pit of frustration. How many kills does the Scout need to get this achievement? 2,004. Most classes only need to kill 1,000 enemies to get their respective achievement.

'A Year to Remember', which requires getting a certain number of lifetime kills.

Some can be obtained in normal play with lots of time, and lots can be 'cheated' if you have one or two friends and an empty server, but some are a cut above the rest: Team Fortress 2 has many achievements that are difficult, ridiculous, or require ridiculously astounding luck (which is inevitable when there are more than five hundred of them).
