Well, it's nice to see that the Witchcap isn't so powerful as an earlier item, but is more useful later on.

LeBlanc will be happy with the Distortion mana cost changes, as she uses that spell quite often.

Most interesting of all are the Kassadin and Elise changes. Yes, they make Elise much stronger, but Kassadin's scaling can potentially be 0.75 per second due to his passive. That means it'll HURT! Considering his recent ult changes, he's probably going to make a comeback soon since he scales better.
