@Riot, Any Particular Direction for Kassadin Changes?

I'm just wondering if you guys have any specific direction for the potential Kassadin changes as part of the upcoming assassin update. I have mained him for at least two years now and have played him through every single nerf since then, so he's obviously my favorite champion (along with Blitzcrank).

Whatever you guys do, are you planning to make him less mobile, or is his identity as the most mobile champion in the game going to remain intact? Also, is his burst going to increase or decrease at all?

Thank you to anyone who answers (even non-Rioters). :)
