The heavy will most likely get spiked knuckles or just run around wearing gauntlets. It's minimal amounts of work for Valve, and new foreign voice clips support it with lines by the heavy like 'My hands are of STEEL'. I imagine it'll pack a bigger punch (lol), but no more criticals.

The shotgun will most likely be another flaregun style sidegrade, where the shotgun remains the superior choice for standard play but the unlockable providing some sort of previously unexplored utility. Maybe he can get a gun that fires a one shot punching glove with a knockback.

This would let them introduce a whole host of new baby themed heavy taunts. "Oh, did BABY get pushed down? POOR BABY!"

I really liked the ideas of alternative weapons when I first heard about it, but with the pyro set I'm just turned off to the whole idea. I love achievements, and they have them down to be a part of natural gameplay with the pyros, but I'm very unhappy with the poor balance of the alternative weapons. Blut/uber saw are complete upgrades, but only mildly and situationally. The medic doesnt' turn into an offensive powerhouse with the lifetap gun and uber charge, but they are much more versatile and well balanced with those weapons in their line up. The backburner though can go fuck itself. It turns the pyro into a skill-less tank of death. The 50 extra hp has to fucking go. Pyros getting back crits while skill walking towards me in a straight line and anyone I'm healing cannot take them down quickly because they have the 2nd most hp in the fucking game. Anymore I play a demoman just so I can lay sticky bombs for pyros. If I can't kill them I'll just explode myself and deny them any points. Fuck them.
