The "O.P.ness" of Mordekaiser (Causal Analysis)

 In the game League of Legends, an online battle arena, there are many champs to choose from, but my favorite is  Mordekaiser, The Master of Metal. Mordekaiser is overpowered if left unchecked. No matter how badly your teammates fare you can always win a game. His most powerful ability "Children of the Grave" lets you take control of an enemy's ghost after you kill them. With this the opposing team's strongest member is now fighting with the people he was wrecking earlier.

Mordekaiser taking the entire enemy team on, by himself.

To deal with this threat there is one simple solution - Crowd Control (CC).  CC is the bane of Mordekaiser, specifically hard CC (e.g. a stun, taunt, or knock up). While CC'ed Mordekaiser cannot cast spells to build up his shield, the reason no one can kill Mordekaiser. Without his shield he is vulnerable, and is relatively squishy, meaning he is rather easy to kill.

So if you ever meet a Mordekaiser you now know what to do.
