So the solution toOrnn's problems is
lowers glasses nerf his Q, which offers immensely more counterplay than his W ever has. Nerf his ult into forever. Buff his passive, which is somehow even less interactive than his W, and buff the brittle proc, which is the reason he's had so many problems in the first place.
But then you're going to say you "buffed" his base survivability, which I guess is true, but you removed an up to 300ish hp shield late game, which you could cast every 6-7 seconds and replaced it with 18 armor by level 18, and 90 base hp at level 19.
This is exactly what I've posted about before, and I will reiterate now- stop removing durability and survivability tools from tanks, especially when they are traded for more damage Literally Riot just posted something about wanting to reduce damage output, so stop increasing it and please, please, please stop removing shields and defensive scaling from tanks, thank you.
