It seems that Valve have been recording everything that we do when we play TF2.

The Rocket Launcher seems to dominate all the other weapons damage wise which, in my opinion, shows that he is a bit overpowered. I also find it interesting that the Pyro's Axe has a longer range then any of the other melee weapons.
