Does Draven Really Need Changes?

Here are the Draven buffs: Spinning Axe (Q) Damage changed to 30 / 35 / 40 / 45 / 50 (+ 65 / 75 / 85 / 95 / 105% bonus AD) from 45 / 55 / 65 / 75 / 85% AD.

Blood Rush (W) Cost reduced to 40 / 35 / 30 / 25 / 20 from 40 at all ranks.

I just happen to see these changes on http://www.surrenderat20.net/2016/12/129-pbe-update.html

What do you guys think? Should Riot go through with these Draven changes or should they not do it at all. For me, I think the changes are intended to fix Draven after he was crippled by the removal of flat armor pen and attack speed steroid removal from Ghostblade.
