Accordingly with tf2stats the Backburner is the least used weapon in the game... no surprise here.
People now realize you really can't magically appear behind enemy lines and no matter which path you choose, there is always someone guarding it.
I won't say the 225 HP Pyro should come back BUT the weapon as it is is pretty unimpressive. Even the Bonesaw have more fans... kinda a feat when you thinks the other option is the Uber-giving Ubersaw.
I am, however, happy with the Charging Targe demo. For Pyros this means less sticky bombs and the Pyro in particular is more than well suited to deal with people at close range.
