I have an Argent Peacemaker which I pretty much use all the time as my gun. So I was wondering, should I sell my Valiance? And if so, for how much? (Neither gun has any UVs.) Furthermore, I don't have 4k CE for the unbinding cost, so whoever buys this will have to pay up front and then I'll use 4k CE to unbind the Valiance. This is obviously not an attractive prospect for any potential buyers, so how can I assure them it's not a scam?
Edit: Also, this is kinda random, but is the player Krogmo really nick? I heard that once but it could be totally made up.
Keep the Valiance. The Argent Peacemaker is good against undead and fiends (except devilites which dodge), but weak against everything else. You'll want a gun that's decent against slimes and constructs, at least, so you can take out polyps and gun puppies from a safe distance. The AP fails miserably against both.
Also, without a UV, your Valiance isn't worth the 4K unbind cost (and only an idiot would pay that upfront because of the scam risk; there is no way you can prove yourself honest, unfortunately). The recipes for valiance are easy to come by so anyone can make his own quickly. Other guns require a recipe from tier 3, but the valiance recipe can be found in Haven.
