Does using a Weapon Skill on an NM mess with the drop rate of certain treasure? I've been hunting NMs for THF equipment and got help from an LS member one time. When I found the NM, I used a WS on it and he was like, "Oooo, you WS'd..." He didn't know of any proof that using a WS on an NM lowered drop rates but he said that it was rumored that it was true. I've browsed some sites about it but can't find anything that affects drop rates other than Treasure Hunter traits.

I'm 0/5 Leaping Lizzy and 0/5 Jaggedy-Eared Jack. I did get the Katana drop from Carnero on the first try, though. I've used WSs on all of these. Personally, I think it's bull. What do you guys think?
