Weapon Upgrades/Achievements

This was a fun idea and quite easy to do for the Medic; all his weapons are unique. It won't be a problem for the Spy, Demoman, and Sniper as well.

But what of everyone else? The Soldier, Pyro, Heavy and Engineer all have the same shotgun (relatively). The Scout and the Engineer have the same pistol (relatively). Valve's intention is to provide "alternative" options (whether or not they've achieved that is another discussion), so how exactly does one give a different feel shotgun/pistol? They're nothing special, they're just back-up weapons.

If Valve is going to give the bland weaponry a class-specific feel, then what's the point in picking the old ones? I know if I ever get the PC version and get the Kritzkrieg, I'll probably stick with the normal Medigun for example.

If I had to guess, I think they might give these bland weapons a "blanket" alteration. As in, when they finally think of something they give it to everyone. It'd also cut down on updating time as well, I imagine...

Or maybe I'm just overthinking all of this. What do you think?

i think they will definatly give class specific upgrades for the backup weapons.

for instance the scout and engie pistol will differ. the engie pistol could possibly give metal in event of a kill or something. BUT i am certain that valve is not going to just simply upgrade a backup weapon such as the shotty then apply it to several classes. take the flare gun for example.
