What I'm asking is to add more Skyrim's silver weapons(+ 20 base damage vs undead/) to the game world(dagger, mace, waraxe, battleaxe, warhammer, bow/quiver + arrows, crossbow/quiver(if they will be from different materials) + bolt.

They should be available to enemies/NPCs, found via random drop, respawn lists etc.

They should be also made upgradable(with silver/steel ingots)

Their reintroduction would make playing as vampire/werewolf challenging.

I'm sure we'll get some new silver stuff in Dawnguard.

A classy silver longsword was the standard equipment for every legion soldier in Cyrodiil. It's also my favourite weapon, not sure if better than steel (probably not) but bonus damage against undead makes it a weapon for every scenario.

The only thing I really want with silver weapons is to return to their original status where they are the only non-magical weapons with the ability to harm ghosts and cause extra damage to vampires and werewolves.

But a wider variety would be nice too.

The silver weapons in Oblivion didn't impress me. They were really just a shinier steel weapon with some decal. But in Skyrim I LOVE them! They're so... standary but unique looking, I know that's kind of a contradiciton. But yeah, there needs to be more silver weapons. I'd like to see a Silver bow, and silver arrows. Silver arrows with a silver crossbow would be really good for killing werewolves.

And I'm going to digress for a moment, but I hope there are wild werewolves added in at some point. I love Werewolves, I want to see more of them. I've always pictured walking down a dark, foggy forest at night, with just a woodcutter's axe, and torch in hand. Being prowled on by some werewolf in the dark, only to have him jump out, and bite me leaving me with the curse of the werewolf. So that I may hunt him down! ( I have a wild imagination )
