Also, someone(cant remember who, maybe ahab) had the idea to make it so the faster you are traveling, the afterburn would reduce faster.

So, if you are a Scout, you get burned by a pesky Pyro, then use a conc to boost you somewhere, it would effectively put your flames out or make them go out faster than normal.

A Heavy's right-click feature could do the same thing or if a projectile-type healing gun were introduced for the Medic, that gun's projectile could also have a similar effect.
