Guild Wars 2

So why is it that certain lvl 80 white and blue weapons sell for so much more on the TP than others (i.e. white lvl 80 maces, blue lvl 80 axes and white lvl 80 shields)? Do these yield more mats when salvaged that other weapons? It seems a little fishy that these sell for 1-2silver buyout when other items of similar quality sell for less then their vendored value.

its because of salvaging, you get a 1 in 4 chance of getting orichalcum ore from those items with a master salvage kit, and since ore is getting back up close to 4s, it would make sense that people buy these to salvage instead of buying ore.

I figured it was related to salvaging, but I thought I would ask. Thanks
