I don't understand you...
How are you 1/3 hp and olaf at max hp with still his ult up?
You're giving hypothetical situations that are making it seem you are being bad.
In a team fight if you are smart and have teammates and say it was 5v4 and Olaf wasn't there, that means you should have killed their 4 and say one of you died or two making it 3v1 vs an Olaf.
Flash is a bad skill and you're taking flash for your own bad gameplay. I don't think Flash is being removed but when I see people with it I just don't think that have the skill to be saying they are good. And to be fair I take flash on some champs, I take it on Annie but not to run away but for my combo.
I heard one person say on here that Flash should be nerfed to the point that if you use it, you get slowed for 1 second after usage.
