Alright, from what I have read and seen: Yorik is considered the weakest champion right now. To that end, I believe it is because everyone starts off with the same track of skills with out varing the skill order along with the items to better the champion. I know this sounds mean and I dont intend for it to be mean, it is just from experience of playing against and with this champion that everyone seems to follow the same skill set.
Now on to what has worked well enough for me when I tried out Yorik during this free week.
I jungled with him, starting with e and picking up w and focusing on maxing e>w>q, with picking one point in q as this is all you really need and taking r when I can. I started at little golems moved to wraiths and then picked up wolves. At this point I had to go back or try for a gank. After heading back, I took blue and went for a gank.
Ganking: Yoriks skills with w and e have considerible range and their base damage increases rather well with leveling them. So to gank, lead in with the slow from w and then hit them with e and then you should be in range for your q and then spam your skills. Unless they escape with a summoner ability or your teammates are not paying attention, then you can get a kill.
Alright to explain skills, your q adds damage to your base attack, not alot, but it adds damage to your base attack. Making leveling this skill near useless as building up any items with attack damage increases the damage more then leveling which is not true for the other skills. That is why you level them up first, so that they are still viable damage dealing skills.
Your ult is kind of useless unless you are turret diving a weaken champion, then you ult yourself before you die and get the kill and attack the turret.
Now, I would like some advice and constructive critism on this build format that I have found some success with.
