I'm not sure if you've ever tried anything like it. Hell, I'm not even sure if it's possible at all, but a few moments ago I was scouting the AH for a new weapon and I came across a decent bow. I was about to buy it when something caught my attention: the icon was red (aka can't use it).
I know for a fact that I've trained the bow skill, because I used a bow from levels 30 to 50 or so, when I replaced the bow with a crossbow from AV or something like that.
What gives? Have you tried losing a weapon skill? It's not the 10s or whatever it costs I'm upset about, hell, I'm not even upset. I'm just baffled, really. Although the thought of grinding up my bow skill from 1 to 315 doesn't exactly make me wanna dance around naked in the moonlight. Or does it?
I'm not really sure anymore.
