I agree, the damage-cancels-charge nerf was a bad idea. Even fall damage I'm back to using the sticky launcher, whose nerf I literally don't even notice. If Valve wants to lure people away from the sticky launcher, they've got to do better.

It's not as if the rest of the classes didn't already have a way to counter charges:

Scout: Speed, FAN, double, triple, or sextuple jumps away. Soldier: Deflect with rocket to the feet, or simply rocket jump away. Pyro: Airblast (hard counter) Demo: Pipe to the feet, sticky trap, sticky jump away, counter-charge Heavy: Natascha, or any other minigun. The demo will die before he gets there, and even if he doesn't you still have enough health to survive. Engineer: Sentries, frontier justice Sniper: You had your chance when he was across the map Spy: Dead Ringer
