It's been asked for, and I shall deliver: my adjustments for Izo.

When Izo lands a basic attack on an enemy champion, he deals bonus magic damage and slows them by %, decaying over 2 seconds. Frozen Edge can only be applied once to an enemy champion every seconds. Izo's next basic attack manifests a wolf head made out of ice on his arm and sends it to bite enemies in a target direction, dealing  physical damage to all enemies and draining their life, healing Izo for  for each enemy champion hit, quartered against minions. If Bolverk Crunch hits an enemy champion affected by Frozen Edge, its duration is increased by 1 second. Bolverk Crunch only procs on-hit effects on the first enemy champion hit. Izo dashes briefly in a direction and receives a shield that blocks up to  damage for up to 3 seconds. Enemies that damage the shield with basic attacks receive 50% of the damage inflicted as magic damage and are slowed by %, decaying over 2 seconds. Izo plants his blade in the ground. After a second delay, an ice spike surges from the ground at target location, dealing   magic damage and knocking nearby enemies out of its 100 radius, where it remains 1 second as impassable terrain before shattering. Izo covers a 1000-radius wide area of the ground in rime for 12 seconds, slowing enemies in it by 10% and granting him 20% bonus movement speed. Enemies that enter the ice field for the first time are also afflicted with Hoarfrost for 12 seconds. Hoarfrost is consumed when Izo hits a basic attack on a target for which Frozen Edge is on cooldown, refreshing it and dealing as bonus magic damage.
 * Passive: Frozen Edge
 * For a bruiser that is supposed to apply consistent CC, being able to apply Frozen Edge to every enemy champion is just better. It's pointless of a cooldown like this to get blown on farming minions. Since Frozen Edge is also likely to be used early for the slow, execute damage creates conflicting purpose, so I removed it. It's funny, I have Primus's own reworked passive just under my eyes and it's basically the same thing, but I think you'll get the differences.
 * Q: Bolverk Crunch Cost: 20 mana Cooldown: seconds
 * Not much of a change here, except numbers and conditions. No more constantly healing off of minion waves, or critting, but in a real fight, you can heal for much more.
 * W: Chilling Dome Range: 425 Cost: 80 mana Cooldown: seconds
 * I liked the harder engage, because at one point, Izo's meant to hit that passive. Also you need to actually attack Izo to get slowed now, because it was not clear. Also the shield scaled way too good. Frost Fang was also not a very good name for this.
 * E: Frost Mountain Range: 1100 Cost: 80 mana Cooldown:
 * Just a little fine-tuning. Oh, and the name.
 * R: Field of Rime Range: 700 Cost: 100 mana Cooldown: seconds
 * I didn't want to change the name on this one, but overall the ability does change a lot. I repurposed Hoarfrost instead of simply removing it, because now it becomes the entire damage part of this ability. No need to jump around or have a nuke with a super-strong slow, the rest of Izo's kit and Hoarfrost can procure me that. Also, interaction with the passive, yay!

I'm not too sure where Izo ends up, he's sort of a strange AP bruiser, but I like him.
