The first 5 things I'd nerf if I could.

1. Event Horizon. Why? Personal reasons. I simply hate it because it interferes with my playstyle. I main divers, it stops divers from diving. Yeah, I'm selfish like that.

2. Wind wall. The benefit is provided against ranged attacks are ten fold, especially in bot lane.

For 1 & 2, it should be noted that I don't have a problem with either of those champs. I think they're in "healthy" spots, i just have a strong distaste for those specific abilities.

3. Iceborn Ezreal. I would just make iceborn's AoE slow effect melee only. I'm pretty confident that Ezreal is the only ranged champ that utilizes it (unless a GP needs extra armor).

4. Which brings me to GP. If you've never laned against a Trinity Force, Storm Razor GP... you don't know he'll. Late game with his Youmuu's and Lord Doms, he'll still be doing 3rd of your max hp per Q. Instagibbed if a barrel smacks you. The only time I see damage like a GP barrel is from a freaking missing health ult like Garen or Veigar.

5. Pyke's execute damage. Late game he can execute squishies at like 95% of their max HP lol
