No, they'd be much worse. Every 12 year old kid will run around just spec-ing the hell out of everyone. Right now this doesn't happen with Korsai because Korsai takes some skill and a lot of patience to get (high skill requirements and a long quest). D claws have no quest requirements and only need 60 attack--no other skills like Construction.
The biggest difference between claws and Korsai is that claws can be used on pures.
don't think a whip would be 10k but yeah. prices would obviously drop to match the d claws in comparison to if they where higher priced. [remember when whips were 1.5? ]
No one would use them, only reason people get them is because they kill tormented demons for them for the 25m drop, think about it if its only 250k hows gunna waste their supplies.and time to get a 250k drop... sure some people going for dragon lumps ect but its still not worth it, the street price would be way up.
Claws are cheap at the moment. Make them cheaper and the failures in dragon med helm, granite plate body and dragon plate skirt will be running around rushing with them.
