Hello guys, I'm Latios Gigetto and today I'm here with this simple Full AD Master Yi build.
I don't really know what I should tell you, so...
GO OUT THERE AND TEACH THE DEVOURER PLEBS WHO'S THE BOSS!

As for runes, take these.
That's it, take these.

I personally think that Warlord's is better than Thunderlord's because of the nice lifesteal you get out of it.
Have you really thought going TD on Yi? You fool.

The Full AD build has a weak early game, but it has a nice mid and awesome late, so...
Try to "elongate" your games, so that you'll become an unstoppable bloodthirsted death machine!
You can either get 100% Crit Chance ,35% Lifesteal and bonus MR, some more sustain or some nice armor pen.

Max Q first(What else?).
Take W second because of the nice sustain. Second max is E, obviously.
Last is W, to everyone's great surprise.

Master Yi is a pretty simple to use champ mecganichs wise, but you have to know how to use his spells;
-Engage with Q and immediately activate E for the true damage
-Red smite for extra true damage
-3 or 4 autos and... done!

In conclusion, I think that Warrior Master Yi is better than Hybrid and you should too!
I've trained a pupil with the Full AD technique and... He got his first Pentakill!
So... this is Latios Gigetto, have a GG, I'm signing out!
