Discussion material again!


 * I'm still skeptical about the Frozen Edge slow lasting seconds, not decaying on top. The fact that its cooldown can now be reduced is also novelty, but ultimately not a big change as Izo will probably not itemize for CDR. The skill in general could use a number adjustment.
 * Honestly, I would've kept the AP scaling. I don't remember how much it was, and it's not noted anywhere, so maybe it needed a nerf, but it deserved a bit more love. AP scalings are what set Izo way apart from Yasuo, especially in regards to this ability. I still don't think the heal is a very good idea, but I've seen worse excuses.
 * Well, I didn't think of a slow so strong, but I see where this ability is going, even though it kinda feels like either you let Izo engage, or you attack and you get picked just because the slow is that long. I'm not a fan of long slows in general, haha.
 * Picture Veigar's Dark Matter? This ability takes 1.33 second to reach its max range (longer than the 1.25 second Dark Matter takes to fall) and is now a smaller AoE, even though it's a little margin. Remember that despite being hard CC, Glacial Blade remains telegraphed due to running underground. I'm not asking for a plain buff of course, but I think you get the point: unless the enemy is slowed, they're not getting hit by this. The simple damage buff becomes honestly irrelevant.
 * A % permaslow is deceptively strong, especially combined with a nuke like this. I am also still not a big fan of Hoarfrost's current incarnation. And Izo still takes second to perform his dash. That makes the 1-second cooldown pretty irrelevant now, doesn't it? I don't know, adding this only gives a clunky feel anyway.
