Well, just use Exhaust.^^

"@anon: what you fail to consider is one word: RANGE. Kog'maw has one of the highest ranges in the game. What does Yi have? He's an EXTREMELY squishy melee carry with no CC. Sure, he can do damage, but only while he's alive. Stun him and focus him and he's dead. He has no escape outside of his ult; compare this to similar champions such as Riven, Irelia, and Tryndamere, who all have at least a slow, ways to escape, and just as much damage output. Yes, Yi is DEFINITELY underpowered. "

That, too.
