I have 347 wins, and don't know how many total played but I've been playing for about a year and a half, and just last week I purchased Yorick. I've been going flat AD quints and reds, full offense with 9 defense, and i get the 7 mana regen trinket as first item, then get the blue cup thing (increases mana regen by each 1% you are missing). I max E first while alternating W and Q.
I have yet to play a game where I have had a really hard time laning or controlling the lane rather, the ranged harassment plus life steal is just so imba, add that an AOE slow, heavy hitting close up nuke, and pets for passive damage and he is my new favorite champion. Dunno why I haven't seen him played more but damn he's fun. Even if you do die in a big team fight, your aoe spell and pets will usually grab you a few extra assists which is always a plus.
Right after berserkers greaves (which are after the mana cup thing with resistance on it) I start working on trinity force, with the slow hammer/mace weapon first (it's late and I can't think of any of these dang names). After I have trinity force, I'll buy a dorans blade just to give me a bit extra life and damage while I farm infinity edge. After edge I get warmogs armor for the crazy life, and finish it off with a bloodthirster.
One thing I noticed is his base movement speed seems to be faster than most champions, coupled with the speed increase from Q and the enemy speed debuff from W. I have consecutively played him top lane and I'll usually end a game with 200-300 cs depending on game length. Overall a very powerful champion and I'd recommend checking him out if you want to switch up your normal characters!
