Pre-Void Kassadin should get a Visual Rework to deliver its concept appropriately

I know Riot rarely reworks skins unless the champion had a Poppy level rework and I know that Pre Void Kassadin is an old skin but the concept right now has so much potential but the execution is so lackluster. Why does a "Pre-Void" man still have a Nether Blade? Why does he still sound like Darth Vader? It's just very disappointing to be honest and the price tag is ridiculous for what the skin delivers.

Yes I know other skins may need a price adjustment/rework for their value (Hint Alien and The Magnificent ) But Pre-Void Kassadin is the biggest offender in this as he still doesn't deliver in his concept

Maybe replace his blade with a regular sword? Maybe remove the Darth Vader noises from his voice? Maybe make his "Riftwalk" animation into a Lunge at the enemy like Rengar? Maybe give him an actual walking animation instead of the supernatural levitation he already has?

Even if it requires the skin to be priced at a higher value I wouldn't care since it would finally make sense, or maybe make it into a "semi-legendary" like Prime Time which is also at 975 RP but delivers its concept incredibly well

TL;DR Pre-Void Kass needs to change aspects of it to fully deliver its concept and be reasonable at its price. It's very lackluster for what it Intends to be.
