Master Yi is the one jungler you can actually PUNISH in the jungle

If you pick a fight with him in the jungle, he has NO escape (unless he has his ult up obviously) except for his ult. But even with the ult it's on a very long cooldown, so you have plenty of time to abuse him when it's down. Other junglers have access to a MS boost, dash, slow, stealth, etc. Something that helps them escape if they get caught. For this reason, I cannot support Master Yi nerfs. Abuse him in his jungle whenever you have the chance.
