Volibear vs Master Yi
So, i just got through with a 1v1 as Master Yi vs Volibear, and i really think he needs to be nerfed just a tad bit. Not much, but just to reduce his sustain a little bit. Allow me to explain: We were both at max lvl, i built on hit with a ton of Max health damage (i.e. Blade of the Ruined King, bloodrazer red jg item, etc.) as well as IE, and Bloodthirster and he built bruiser. Now, with the itemization on us, i should be doing more damage than he can heal, as he didnt build any lifesteal at all... 0, zip, nada... And yet, he could take my e'd ulti plus red smite and still come out on top in every fight.
Under tower? Dead. 2.5 minion waves? Dead. Under both nexus turrets? Still dead. I don't see how or why i cant kill him, simply because his passive kicks in.

into full tank and he drops like paper without even dealing damage to you. Lategame Yi is way stronger in 1v1 than Volibear.
