IMHO, item choice and skill really makes or breaks this guy early on to mid-game, as well as summoner spell choice.

Master Yi is an awesome melee carry

The problem with this is that melee carries suck

It's funny that the champs that do the most damage are ranged, anyway. Melee is gimp to the max.

I bet to differ. Melee heroes have much higher damage. They have better movement speeds. They have strong crowd control, for the most part, as well. Yi's abilities are defensively offensive. He can alpha strike in order to be untarget-able for a while and then he has highlander to chase and then highlander to run after he kills.

Wuju style makes him do great damage and all he needs is some items and a good player to make him shine.

I have seen plenty of Yi's win games with insane damage. I've played on teams where a Yi farmed for 45 minutes while we were getting devastated in all team fights and then decided he had the items he wanted and we won the game on the next push.

Absolutely moot point.

If he was playing a stronger character, you could probably just have won the teamfight.

He's not very useful, and has no AoE.. if he doesn't get fed, he can't do much of anything.
