BoogalooYet pyro is only viable in very limited situations in 6v6 (i.e. holding last with an uber disadvantage) and is far from the most important class in HL. If pyro is so overpowered, why is it not very useful in the vast majority of competitive play?
pyro is only "overpowered" within its niche which is close combat, but once you reach that sort of range against a pyro it's very frustrating to play against.
