Its the new demoman weapon of doom 


Flare guns are handy then. And who says the pyro cant use a bit of teamwork too. Find a competent spy and while the heavy is busy with with you, the spy stabs away. God knows ive had that done to me. Of course, im not considering the fact that to do that, the spy had to get through all the spychecks...
A good pyro can only take out terrible full health heavies, let alone overhealed ones. The heavy is the pyro's hard counter.
Flare gun is useful for annoying people and in conjunction with the axtinguisher, which is still not enough if you're going against a heavy from the front.
Backburner will maul a heavy that doesn't watch it's back.
Unless the medic turns around and spots you, by that point, I go for his patient. I had that happened to me on a couple of occasions and was forced to change targets.Spy should backstab the medic first anyway.
I have killed a couple of people by repeatedly hitting them with the flare gun. The axtinguisher is good for those flame n axe runs. For a heavy it takes about two strikes to take him down. And that is if youre lucky and have a heavy who is not paying attention. Normaly if the heavy is being hit with an axtinguisher, he's gonna spin right to you and fill you with lead from his minigun.Flare gun is useful for annoying people and in conjunction with the axtinguisher, which is still not enough if you're going against a heavy from the front.
