The thing is, pyro still isn't that bad. He got hit where the sunshine resides, but he still stands tall. While they took away his power to combo (puff n' sting), pyro can still output damage. I have had no issue within the past couple days using the decreaser and stock shotgun. It's slower by a noticeable ammount, but the switching is still faster than any other flamethrower (which is really nice). The damage reduction on the degreaser was removed, which means you can w+m1 a person to a remote location just fine and finish them off there. Now Valve didn't do anything with the flare guns. That honestly surprised me. The random crits on top of the set crits seemed broken. I remember the TF2 subreddit worrying hard about a potential nerf for the flare guns. Glad they didn't. The axtinguisher got nerfed for the hell of it. I don't know many pyro mains who actually used that. Most of them still used the powerjack for the mobility. +25% move speed is help, especially in competitive events like Highlander. Even though the axtinguisher got nerfed a few updates before Tough Break, it's finally done.
Over all I think pyro is more of a utility now rather than someone to be offensive. Deal damage where you can, but air-blast teammates that are on fire, spy check, reflect projectiles, etc. It's a new age of pyro that I hope will be reverted somewhat, but I can only hope.
