The Pocket Pistol makes the Sandman viable for aggressive plays since it puts your health back at 125 at the cost of fire vulnerability and having a slower cleanup weapon, giving the Scout 30% bullet vulnerability would make it even less viable than the Candy Cane, and the idea is to expand the active weapon list. It sounds like this is the sort of thing that Robin was talking about: there's interesting strategies and combos for people to experiment, play with and counteract but instead of trying them out they'd rather trim things to suit their comfort. There are lots of weapons that need balancing- and the Pocket Pistol having no visual indicator of a health boost is one of them, as it conflicts with every other health-boosting item in the game- but if you want to see a weapon re-statted entirely then a pick/ban system will produce real data on what gets banned and how what gets used performs under clever abuse.

Instead of saying that X weapon needs to do Y and Z instead for no other reason than you think so- something Valve has undoubtedly heard a trillion times without any data to back it- play with and against these weapons and let them see the impact these weapons have on a match, and then they have solid ground to make changes from.

I've honestly never had more fun with this game than in the wake of Robin Walker calling it boring, where people are starting to set aside their hangups and experiment with weapons they were afraid to use to make really cool new plays their opponents aren't expecting. It's a wild west era and I hope it grows into something wonderful, and I really hope the people who would fight against it don't kill it before it can blossom.
