Its damage is good, it’s just for pyro it sucks for when there’s more than 2 people. I main pyro and I just use the stock over it, and I’m able to mow down heavies just by using it, and the airblast is so horrible.
If you're not used to using it, it's ass. If you have experience with it, it's overpowered due to the extra damage when firing on afterburnt opponents.
