malady >>> Calling. Mainly coz of your AD from Wuju. You need that AS early game to get double strike procs more often. So even on crit build i would stick to Malady/Stark instead of calling.

malady is ok if your not going crit so for a crit build you have to go with executioners calling. its a must for the cheap early game crit.

Ok the idea is nice. Crit Yi is viable, items are ok, runes kk (still prefer ArP but idea needs sacrifices :P)
Masteries ok, pretty much standard but i would go MRes 3/3 instead of Armor 3/3 :)

But than i saw the skill order... Fix that... FAST or the guide will get -1245152 rating and ppl will not see it :)

Also a description would be nice... i dont find "basically your crit chance is redic which results in rape" as a desc, you could just put " . " in there. We see that this is a crit build even from the title, believe me mate, we are not THAT blind :)

Write something up, be creative coz this has potential.
