Ranked Solo Q and how to win.

1. ban yi,xin,jax,udyr,tahm,zed,raka,mundo,graves,garen,etc...
2. pick karthus mid or yorick top.
3. farm until either level 6 with karthus or you finally get pushed out of lane by the enemy jungler ganking top for the 9th time as yorick
4. now because all you team's other lane and/or jgungler has fed their opponents and you couldn't do shit about it, use your kit to make up the difference by either ulting the most fed person on your team as yorick, or just press r as karthus every time you see one of them low, so as to make the team have an advantage in every fight (5v6 or all 5 opponents start with lower health).
5. Cry when even though you are fed, your team is still awful and end up costing you the game.

Alternative:

1. Play Yi, Xin, WW, or Udyr
2. Get sated
3. Acquire cancer (rageblade)
4. Become cancer to the enemy team
5. Win by being more or less immortal unless the enemy team throws all the nukes at you, allowing your team easy kills since the enemy's abilities are all on cds
