Can act similar to a sticky in a defensive way to control the enemy team
-Shoots a ball of fire that spreads on the ground/ wall, leaving an area of fire that gives afterburn damage to anyone who steps on it or goes near it. Staying in the trap deals extra damage (half what the flamethrower deals per second)

-If it's on the floor, it ocupates the area of 1 player (a third of the average hitbox, the fire could end near the waist). If it's on a wall, it ocupates only a third of a player's hitbox, from foot to head. I should draw this

-Can't be avoided by a simple jump, yes by a dobble jump by scout, maybe by a crouch jump

-Can create a total of 3 of this fire traps, each one disapears in 1 minute (not sure about this), and can be turn of by the enemy weapons that extinguish fire.

-Pyros of your team can extend the time the fire is alive by airblasting it, and you can also, but is not convenient for you since it costs more metal than just creating another fire

-Has half the range the other flare weapons have
Well, I'd like to see this in the game, since the pyro can have many roles, why not enphazise that? It could be very useful in many situations. Also, you can still combo with your mele. The idea is here, but I don't know so much about balance
