You're right with one thing. The scaling.

Skullcaver had 'low' damage in exchange for the possibility to stun, which WAS pretty annoying for being a 1/4 chance on stun.

The stun problem has been taken care of, but what for? Now it doesn't do much damage AND lacks the possibility to stun.

So yeah, Skullcaver should be set to 90% STR. Without upgrades, it's pretty much the most lack-lusting Axe in existence. (Heck, it can't be rebelled for damage, so why the lack of scaling?) It lacks to accomplish the Axe's role of being 'deadly', damage wise.
