People need to understand the difference between a strong kit and damage
Even if you took out the scaling damage on Yasuos Q, he would be almost the exact same because of his kit. A kit makes a champion broken, not the scaling or damage that they put out. Take Fizz for example, other champions have much higher scalings on there abilities, however, it's the WAY Fizz dishes out that damage, that makes his 200 AP burst, higher than an Ahris 200 AP burst. Food for thought.
could have lower numbers in his kit and I'd still say his kit is good. Of course I'm happy the numbers aren't lower....
