When TF2 was released I instantly disliked how many weapons where stripped away from the classes in comparison to the old Team Fortress CLassic game.
I really disliked it how the Pyro lost his incendiary rocket launcher in TF2.
With the new weapon updates - and the much apreciated Flare Gun, now the Pyro Class is more closer to what it was on TFC. The TFC-levels that the mod community has made also helps.
