Master yi will gain 40 attack damage per second against enemy champions

2.5 attacks per second

rageblade + doublestrike = 2 attacks per auto

that means 5 attacks per second

melee champions gain 8 ad per attack

8 * 5 = 40.

So if the fight goes poorly and master yi manages to catch out a tank, he can kill them over 5 ish seconds gaining up to 200 attack damage near the end, swap targets and only lose half of that. He won't even have to catch someone out if he just builds super tanky (like guardian stoneplate + steraks)

With all this free attack damage converted into true damage through wuju style, and an explicit reward for just building up a ton of stacks before pressing E to blow up everyone, prepare to see tank yi emerge again.
