The Pyro is one of the best starter classes. The flamethrower can kill relatively easily. It is often said that the mantra of the Pyro is W+M1, which is so true. A newcomer to Team Fortress 2 can do alright with the Pyro with no strategy but with a strategy, the Pyro can be an essential class to any team.
So, down to the meat of the Pyro. His or her, we’re not sure unless there has been some news that I don’t know about, if so comment! His or her main strategy is, ambush. The Pyro’s flamethrower doesn’t have very good range yet it is very powerful. Using flanking routes, a little bit like the Scout can benefit your team immensely. Especially if you have the Backburner which gives you 100% crits if you flame your enemies back, it is extremely important to attack from behind, especially if you need to take down a Heavy.
A more supportive strategy is called spy checking. This is very important when protecting the objective or your Engineers nest. Spy checking involves you puffing or full on flaming your flamethrower in areas that are vulnerable to your team, for example a capture point, the intelligence in CTF, an Engineers nest or even spy checking around a Heavy and his pocket Medic to make sure they don’t get killed when making an important push.
These tips are more for fighting against other players and helping your team mates with your compression blast. The compression blast is a blast of compressed air that can either push enemies back, reflect rockets and other projectiles and extinguish team mates that are on fire. Pushing your enemies back can be extremely helpful, even if you die it’ll give time for other team mates to push the enemies back even more. It is most effective if you push a Medic away from his Heavy. The Backburner uses a lot of fuel when using the compression blast so use it wisely. Extinguishing your team mates is extremely important. I can’t even count the times I have ran circles around a Pyro to try and get his attention to put me out and I die. Extinguish team mates, it makes you more useful and you get points for it.
One last tip, if you are going head to head against a Pyro, keep your distance and get out your shotgun, unless attacking from behind and you have the Backburner or if you catch him off guard, burn him up. It is harder to burn a Pyro because of his/her protective suit.
