I have only one thing to say about this Ryze update
Thank you Riot for reworking his ultimate. It was just a bunch of free stats which just made Ryze pretty unhealthy to fight against. With spellvamp it was impossible to outduel or outsustain Ryze. With movement speed, you couldn't flee from Ryze at all. And if that wasn't enough, giving him free cooldown reduction also allowed Ryze to build other items with more raw AP because he didn't had to itemize for cooldown reduction items which had less AP.
Free stats abilities and passives are almost always hard to balance and unhealthy (seriously, the only exceptions I can think are Singed, Nocturne, and Vladimir). While one can argue that a 5-man teleport is going to be pretty powerful, I am sure that Riot will balance this ability with a very high cooldown and/or with short range.
