Morde rework breaks record statistics
Mordekaiser was a champion who used to go to solo top where he maintained a win rate of 50.5% http://champion.gg/champion/Mordekaiser/Top
or he would go solo mid where he'd maintain a 49% win rate http://champion.gg/champion/Mordekaiser/Middle
Riot realized this champion was unhealthy and could not be balanced so they undertook the most ambitious rework ever seen in league history
As a result Mordekaiser has broken record stats across the board
He is now the best ADC in the game with a 56% win rate http://i.imgur.com/At0EDbj.jpg
He is now the worst support in the game with a 43.8% win rate http://i.imgur.com/trWzFPg.jpg
He is now the worst top laner in the game with a 41.25% win rate http://i.imgur.com/pZf8jRb.jpg
He is now the worst mid laner in the game with a 39.54% win rate - and the only mid laner in the 30-40% bracket http://i.imgur.com/YM49W2X.jpg
I'm not sure what riots goals were but either the morde rework has been a success in the sense that they've killed off the the viability of solo lane morde and forced him into the bottom lane where he is dominant or they've failed at trying to make a healthy balanced champion that can fill multiple roles on a team
and
without wasting the AP. If i remember correctly, riot did that to nerf him and people thought he would be worse, but then people learned the benefits to it and it only made him even more menacing.
