Is Susan ok right now?
I don't know much about his history and I've never felt frustrated playing against him in a toxic way. He's like this ticking time bomb that you threaten to tick faster if you mess up a gank, all you can do is make sure he's not pushing his lane and let him play with his food in top lane while you try to destroy mid and bot before he decides to start roaming.
When he starts roaming it's genuinely terrifying. Have you ever fucking seen Susan say: "okay that's probably enough stacks"? Have you fucking seen the face of terror? If you can't close now, you're not going to close! It doesn't matter how garbage his team is, nothing stops that train now, and he only needs one lane.
I'm okay with a champ being like this, I think it's really cool. Please don't nerf Susan!
