Master Yi PBE 6.10 indepth analysis
In before people think this is a hate post on 
, I love playing because of the speed you get from the ult and itemization (
) that helps him get even faster. Anyways, after seeing the change they are about to make to and 
, I just felt like he is going to become top 5 banned champion, again. That, I don't want to see because I play him in ranked and usually does quite well with him, at least until patch 6.9.
The thing that happened in patch 6.9 is that Master Yi can't really build tank anymore because the damage is lacking. But if he goes full AD, he would be decimated easily unless he does the clean up. So, he can only be a janitor. While that is not bad, it is also not good.
Patch 6.10 is like a savior to Master Yi. If you haven't checked, Patch 6.10 in PBE buffs 's Wuju style's actives bonus true damage from 12/19/26/33/40 to 14/23/32/41/50. Now people might say: "it is 10 more damage per hit, give it a break". Yes, 10 true damage per hit on an assassin build is not that much. But this 10 damage revives the tank Master Yi build. Also, gets 10% extra attack speed and has a 4% max hp shred instead of 3%. Now this is not just revival, this is Jesus picking you up, washing you off with holy water, and blessing you with holy power.
A possible 6.10 tank build can be: 
. The core is obviously . Here is why this build or builds of similar pattern will become "over-powered" again.
- Pro: Rageblade alone provides Wuju Style enough damage to match the damage before patch 6.6 (The nerf on E).
- Pro: Less farm, more ganks.
- Pro: Bloodrazor deals 4% max hp as ad instead of 60 magic damage.
- Con: Rage blade deals 20-30 less magic damage on hit, and cost 800 gold more.
- Con: The double on hit effect triggers on 6th attack instead of 2nd.
From the above, we can see that the only real set back is the time it takes for you to get to full power during a fight. However, with four items that gives you survivability, you are now capable go getting to that state. The 4% max hp out scales 60 magic damage by miles, however the remove of scaling damage on the Rageblade does hurt a little. The 800 gold cost seems a lot. However, you can now gank a lot more. This means, if you are good at ganking, you will be unstoppable. So basically, the tank Build's damage is back and better but it takes time to build up that damage during a fight.
The conclusion is, this update lifts Master Yi out of the dirt that RIOT left him on with the release of 6.9. However, it gives him too much potential, making him unplayable due to the high ban rate.
Extras: I wonder what is happening in RIOT's balance department. It is like, your father gives you a monthly allowance. But realize it is too much because now you are buying things you shouldn't be buying, like books and stuff. So he cuts your monthly allowance down to half. And then cuts some more because you are still buying books! One day he is like, "you know what? No more allowance for you". After one month, he saw that you lost 20 pounds because you didn't even have money to buy food. So he starts giving you monthly allowance again, with doubled the amount! God bless.
==> if you're fed enough to reach that point you just ascended in summuner's rift, you pretty much one shot anyone who doesn't have at least 2 defensive items, get resets, rinse and repeat).
In most games its not realistic to go strait for full AD/crit build, but 2-3 damage items before going defensive goes a long way.
The only reason why you would "have" to go devourer before was the insane cost efficiency of the item once it was sated (and it's synergy with Yi's E). But now, going warriror is totally better in most cases IMO (unless they have a lot of tanks that you will have to deal with). If you're kinda fed, you can afford to go
