If nothing, Kayn's ult needs a buff

"deals massive damage". Im expecting to see a good chunk of HP gone on the enemy. Turns out it dealt barely 150 damage. Its for Kayn and Shadow Assassin form. Not sure about Rhaast. Didnt play against too tanky champions so i cant tell. But imo, unless fed his damage is lackluster. And his "assassin" form isnt so satisfying. He's more sustained damage oriented than burst damage. So if you go 1v1 against any real assassin with full glasscannon build you will get oneshotted before you even do your WQ combo
