I played Yoric for a while when I was level 10 and loved him almost immediately. He was tanky, he had these little pets, he could do a bit of burst, and his ult was instantly my favorite. While I basically love all the shadow isles characters (except with Karthus, I don't really enjoy playing him for some reason), I really want to pick Yoric back up now that I'm level 30.
So I need help with runes and a basic build 
For runes, would AD or Apen be better for marks? For quints, AD or something like Mspeed?
Build I'm thinking so far looks like this (general, can change based on the game)
Start armor + pots or pots +ward, shoes + pots in normals.
Build Tear + boots first back, half or all of Iceborn Gauntlet next back, finish manamune + upgrade boots, then warmogs and atmas. Put a Spirit Visage in there somewhere in there if they have lots of AP, since it has the highest ap in the game, gives me more health, cdr is always gold on Yoric, and it makes my E that much better.
Thoughts?
