If there is one thing from classic EQ that I remember vividly, it is the fact that dervish cutthroats (WC, NRO, oasis, SRO, and wherever I'm forgetting) dropped bronze weapons instead of rusty weapons.
I have played on this emulator awhile now and I don't think I've ever received a bronze weapon from a derv and I've leveled up a couple characters around this level now. I am 100% that they dropped bronze almost every time that they had a weapon showing, and that I use to preferentially pull the ones showing bronze weapons to try and make money.
I tried to find some evidence, here is a link to allakhazam's website regarding dervish cutthroats.

I searched and didn't find any previous posts regarding this. I hope that this gets changed. Thanks and I hope that I could help.
