Darius' winrate is now on par with Morde's top

Statistics are hard

First off cite your source, I'm assuming you are using champion.gg (http://champion.gg/champion/Darius/Top)

To start this off his win rate is 46% overall, not just top lane. Top is just his most frequently played role.

1. If we look at win rate % by patch we see he has dropped sharply since the last patch (the one with kindred being released) from 51% to the aforementioned 46%.

2. Additionally his play rate % by patch has seen a rise after the last patch from 3.47% to 4.44%. This may not seem like a lot but overall it is a decent increase in the number of games he is played in.

3. We can also see from his win rate % by games played that at around 5-15 games on darius, they have a 46% chance of winning. where as if they have over 125 games, the win rate is 55%

So, with this in mind, what seems to be happening is that with the release of kindred and them taking up a ban slot, darius is now slipping through the ban phase and getting picked up by people who don't have much experience playing as him and thus being bad and losing games. additionally these statistics are plat and higher so anyone who sees a darius picked up will know what to do against him and coordinate as a team to kite and kill him, thus making darius lose more games.

(side note, his most frequent skill order maxes his w after his q, this is pretty good proof that a large part of the Darius players don't know how to play him if they are maxing w before e)

EDIT: just took a look at mord (http://champion.gg/champion/Mordekaiser/Top), his win rate actually rose from 43% to 47% in the last patch. neat

On top of that Mord has a bunch of other problems and is a completly different champ than darius. This thread highlights them: http://boards.na.leagueoflegends.com/en/c/gameplay-balance/RTuNEq9Q-im-the-guy-who-created-morde-bot-not-riot-now-i-have-a-bone-to-pick

he focused on mord adc however he touches on mords problems in general as well.

Will still get banned. Until his kit provides nothing and only nothing. Here is an example. His pull deals 0.1 maximum health and his Ult heals them instead. His W gives them a free for FREE! And his Q will take him a year to swing that shit. Oh yeah his passive will be "Bloodrage" and he will give them a passive to them. He can also hit his allies as well. Now we have fixed up a Support from the Noxians, why not the General himself be the support of the ADCs.
