a little tip for ornn - u can buy a refilable potion only at the beginning and after just use ur passive to get Doran's item. 18:28 right after Q u should use R > E > R and this Kata was dead)
Stacked Smolder doesn't always win. There are some champs that are able to counter him. Yasuo can hard counter him with Windwall early game; making it hard to get stacks. Any health stacking champ can literally out tank him. Mundo is probably the best example of this at the moment. (This made worse by how bad anti heal is atm.)
