As far as lore go, Izo should be free of the factional war in Freljord, but in a truly independant way. Read: He does not want any part of it. I was not referring to his title by the way, but to the skin option. Izo's only way to the throne is to kill them all, and it's just not happening.

Q: I don't have any right now. Frost Bite would be literally and figuratively super legit, but Anivia's E is called Frostbite, so...

W: My suggestion would've been to tone down the range of dashes for the ultimate, keep the dash here, and make it so that enemies get slowed if they attack the shield. Not the greatest, but this makes it so that Izo's niche is a fighter with immense amounts of CC, but much unlike Nautilus, it's softer but more consistent CC, on someone that will eventually die and deal a lot of damage, compared to Nautilus' usually harder CC (also harder to hit), lesser damage (at least he needs a lot of time), and better tanking.

E: 200 diameter is not that big. It's half of Anivia's level 1 wall length. Or just a bit less wide than a Trundle Pillar.

R: To tag multiple enemies, make it so that you don't have the area spawn point blank. Trundle's W has a 900 cast range and makes a 1k-wide area. That's mostly what I was thinking about when I saw Field of Rime.

Also, as a side note, targeted dashes usually have at best 700 range, like Kat's Shunpo or Akali's Shadow Dance. Only two ultimates go farther: Diana's Lunar Rush has 825 range, and Vi's Assault and Battery has 800.
