Alright, since it came up and someone on Tightrope was wondering why people dislike the new Pocket Pistol so much:
I have nothing against "no fall damage", that's fine and synergizes with the Blaster. The lower fire rate can stay too, gives it a different (arguably better) feel. But the +health I see as potentially a big issue. It's even still perfectly usable as a pistol, and Pyros aren't actually a common problem for Scouts in the first place.
+max health for Scout is theoretically acceptable, needs a huge downside though because Scout and Spy are meant to be the most fragile classes. It's just like giving Heavy extra speed, goes against the class definition. Scout is never supposed to tank, his survivability comes from mobility. I really don't like +max health on Scout and the Milkman Set as precedent is another good argument against it.
It being passive and hidden is a big issue. I can't stress it enough. As long as the Pocket Pistol exists as it is, you will never know if any given Scout has 125 or 140HP. Health penalties are more acceptable because they let fights go in favor of the enemy, though even they aren't ideal, but a health bonus screws up all prediction as it increases the number of shots needed for a kill. Even with a big downside a hidden +max health is not a good idea.
Items in the game that add max health:
Milkman Set - visible hat and set weapons
Eyelander - visible glowing eye with 4 stages
Wee Booties - visible shoes
Gunslinger - visible arm
Danger Shield - visible shield
Dalokohs Bar - hidden but temporary, might be able to watch Heavy and hear eating etc., still bad
Pocket Pistol - completely hidden and permanent, not even guaranteed the Scout uses it to shoot
On top of all that, at full overheal a Scout has 210 health this way and can survive two direct pipes/rockets in the face now which is just unwarranted as it's already very difficult to do against decent Scouts.
One more thing - the Atomizer is by far the best Scout melee right now. Thanks to the Pocket Pistol being an upgrade (and usually Mad Milk being banned), it will be basically mandatory as well. What's that, Pocket Pistol+Atomizer have even more synergy together due to 15 more health for triplejumping and no fall damage being taken? Well balls.
