Why even let anyone other than CertainlyT rework champions?
By far when it comes to VGU's the quality of CT's are incomparably better than everyone else's products.
Warwick and Akali are indisuputably the highest quality VGUs we've seen to date. They've made both champions much healthier and more modern while (and this is the most important part) remaining faithful to the original spirit of the champion. The only other VGU to come close to CT's high bar is Evelynn.
There is no "delete your champ and replace with generic, marketable garbage"
There is no "just make them a tank"
There is no "just give them everything and hope it works out"
There is no "just make them shit" 
Do I even need to say more? Outside of Akali's current numbers just being a bit too high, she's a very well designed champion and simple number tweaks will place her in a perfectly acceptable position. Warwick is one of the least offensive champions ever since his VGU and has barely appeared on the patch notes.
Honestly, as much as I dread the "inevitable" Volibear VGU, because he truly and honestly does NOT need one, if CertainlyT is the man doing it, I don't think I have to worry about any of the above happening, because CertainlyT has his head on straight and a clear passion for his work.
VGU devs, take note. CT is three times as good as the next guy.
