Here's the issue, Swords are a versatile weapon, Lightning is a versatile element due to the nature surrounding it's builds, such as materials like Conduiz, and then on top of that the lightning sword's scaling is versatile, thunderhooves exist to further benefit these builds to make someone even more versatile, and then with it's scaling it's able to push other lightning themed weapons out of the way because of this.

I'll re-iterate, lightning is way too powerful an element to give this scaling, also it doesn't just take away from other lightning themed weapons, it also just takes away from the sword pool, why ever run Sanjin, Fuuma, wo-dao, Hakouhen Katana, the new katanas that have STR scaling, when you can run this simple to stat for weapon.

You either change every katana and lightning themed weapon to SKI scaling or you chop away the pure SKI scaling of this weapon, like I suggested before would be good enough: 25% STR, 50% SKI, 25% LUC, this way if you want to stat for damage with this weapon you can, by building a damage stat, or you'll suffer with a mediocre 75% scaling if you go pure SKI/LUC, it's fairly simple really.
