Nice trolling attempt, it's fun that people take you seriously ;)

i am very sorry oldben, sorry for this build

You should know one thing - people on MOBAfire are expecting complete builds for their champions. And complete build MUST include runes, masteries and summoner spells - all for player on level 30.

Maybe I don't need masteries, but they're really useful - and mixing 3 different trees works only in some cases. Yi isn't one of them.
And if you're setting them, give 30 points.
I'll show my setting:

Offense tree:

* Tier 1 - Summonner's Wrath(1/1), Brute Force(3/3)
* Tier 2 - Alacrity(4/4)
* Tier 3 - Weapon Expertise(1/1), Deadliness(4/4)
* Tier 4 - Lethality(1/1), Vampirism(3/3)
* Tier 5 - Sunder(3/3)
* Tier 6 - Executioner(1/1)

Defence tree:

* Tier 1 - Resistance(2/3), Hardiness(2/3)
* Tier 2 - Durability(4/4)
* Tier 3 - Veteran's Scars(1/1)

Don't you think this is easier and more effective way?

Items are not bad and my usual build is pretty similar, but I repeat once more - Thornmail isn't enough. Frozen Mallet would be much better choice, but you should pick it earlier(my suggestion is before Phantom Dancer).

Once again I encourage you - read Jhoijhoi's Guide about Making a Guide. You won't regret it.

I am very sorry but you dont need the masteries as you can kill without them just please try the build

You have to try harder.

Sorry bro, but this is simply bad. Masteries don't make bigger sense, you haven't picked summoner spells, and text is painful to read.

Check jhoijhoi's guide about making a guide and try again.

P.S. One Thornmail does not simply make you a tanky DPS.
