Yorick has the 4th highest base HP and 3rd highest base AD, armor, and is tied for best MR.

For a champion that utilizes Trinity so damn well, this is straight up busted.

Why the fuck are Yorick's base stats so insane?

Umm, cause he's a tank?

He's actually a juggernaut. I wouldn't mind these base stats, except that his extremely high base hp, armor, and his base ad make destroying other top laners incredibly easy once he gets sheen, and pretty much guaranteed once you have trinity force. There's a reason that champions who have that high of a base AD don't have synergy with Trinity. Because it's broken.

The champion that comes closest to that level of base AD that uses Trinity is Jax.

You COULD make an argument for maybe Poppy, Gragas, etc but they don't synergize with Trinity nearly as well as they used to.

His winrates are pretty skewed at the moment:

But it would appear that the reason his winrate is so insanely low at the moment is simply because 90% of the people who are playing him have less than 50 games experience on him. However, when someone starts to master Yorick, he has a staggering 69.9% winrate.

That's insane. So a good analysis of this data, within a reasonable margin for error, is that once players learn how to use him, he's damn near impossible to beat. In fact, from personal experience, the only time I've ever seen Yorick win lane is when the jungler camps him. Hard. And god forbid Yorick win lane. That fucker pushes ridiculously fast.
