Mamma mia, here we go again... :) It's sweet how Izo keeps getting updates. I should definitely put up a recommended list in my signature, just to put Izo in.
 * P: I think the passive nerfs help avoid the overscaling. I don't know if 120 damage is still too strong, but we need Izo to be able to scale up, so I think with the global nerfs he's in the right place. Good, definitely, but not too much.
 * Q: I don't feel I have to talk about this ability. Bolverk just gets to nomnomnom less HP out of minions. Which is a bummer, but very understandable.
 * W: I'm sure it's kinda good now. Would be too reminiscent of the existing one if it created an aoe grounding now, wouldn't it? ;)
 * E: Uno nothingo. Yeah, zip. Squat.
 * R: In 3 words, I love it. That Hoarfrost AP scaling still tempts me to play him with or something.
 * Just a little note, assuming there's an enemy Izo in your Field of Rime, movespeed calcs: 350*0.85=297.5 350*1.2=420 (419 due to the 5 points over 415 being multiplied by 80% = 4). 420/297.5~=1.4... Merely for being in the field, you walk around 40% faster, and that's level 1 Field of Rime with no boots, and Izo is a fast champion with his 350 MS, so slow champions would be even more outsped in that zone. Not saying it's too strong, but it's definitely not weak.
