How many times must I say this?
Xin needed buffs, do I agree with the current buffs? No.
I personally wanted a buff on the dianemeter range of his ult knock away so he could be a living gragas barrel.
But on subject
Xin is a Devourer attack speed styled jungler, if you were to compare him before this buff to any of the other Dev Junglers you would realize he was the worse out of all of them.
You had no reason to ever pick Xin over

None, you had no arguement, their was no arguement, he was the weakest out of all the dev junglers that I listed, when a champion is the weakest in a play style or job, that is when he deserves a buff.
Do I agree with how Riot did it? No. But to say he needed no buffs is idiocy.
