I personally even like his proposed mechanic, but adopting it wouldn't be necessary: I'd be fine if they simply abandoned weapon skill entirely and just based everything on your character level to start with (so that if you were a level 80 paladin and you got a new hammer, you'd automatically hit with it as if you had a 400 weapon skill, no muss, no fuss) if you're dead set on keeping things simple. No matter how they go about it, since training dummies still don't provide weapon skill on use, I'd have to believe that some change or revamp of the system would be a very nice improvement to the gameplay. Getting a nice drop shouldn't send you into the Blasted Lands to find Servants of Razelikh. Those poor guys -- not only are they cursed to be unable to die, but they get smacked in the head by guys way higher level then they are all day. It's a hard life being an unkillable mob.
If Blizzard was a pixie one could make wishes to, this would definitely be one of mine. Also, I'd try and keep them safe from Captain Hook.
