Volibear's w is basically a darius ult

first off, no I'm not just some noob crying about voli when he is finally becoming viable again. I have had this complaint ever since I first saw volibear. his w, at all stages of the game, does way too much damage (all the while building straight tank). you go in to fight him level 1 and his w executes you from 1/3 hp. you go in to fight him rank 18 and his w executes you from 1/2 hp. I literally take less damage from darius ults. the problem is the health scaling. no other tank in the game has any health scaling for ANYTHING that high. it doesn't need to be anywhere that high. at the very least, it should have a large chunk of the health scaling changed to ad scaling.

edit: im not asking for his w damage to be nerfed to the ground with a 10% health scaling, I just want a large chunk of the health scaling to be shifted to ad scaling.
