They should make pre-void kassadin a legendary skin
They could do it so easily too, all he would need is a retexture. And for an added bonus, they could get his original voice actor and remove the effect they do on his voice, so you just hear human Kassadin speaking, Examples of what they could do for what he would say: Walk: 1. The void....It is trying to take me... 2. Not much longer now.... 3. You should all fear the void... Ult: (at the beginning of each ult stack) The void will consume you all! Joke: (Looks at void blade) You know, I actually like this shade of purple. Taunt: (Looks down at arms) Just because I have no control, (Looks forward and points with void blade) doesn't mean I won't enjoy it!
