If he's the last pick and you see that the other team has no hard CC, yes, it can work. --- Excited for: MHTri U, Fire Emblem Awakening, FFVSXIII (It will come out... eventually. Right?) Dissidia 012: Main:Terra Subs:Squall,WoL,Cloud and Kain.
If the other team don't have CC and you only engage in skirmishes/split pushing he's really powerful. He can keep the enemy team unbalanced, wasting their time and resources to try and stop him. --- http://www.gamereplays.org/community/uploads/post-396-1161708490.jpg :: sound advice from the NHS "I like FosterTaken" - Darth Snake
Even if the enemy team has CC, Yi isnt much of a full on 5v5 team fight contributor anyway. If you play Yi, try to cleanup and keep the enemy stagggered by split pushing or backdooring or what have you. And ward everywhere. --- HAF 922 - i7 920 Nehalem @ 4.0 Ghz - 12GB DDR3 Patriot 1600mhz - ASUS P6T Deluxe - EVGA GTX 580 3GB - Cooler Master 850W
