Darius is by far the best Juggernaut, please fix

On this page http://boards.na.leagueoflegends.com/en/c/developer-corner/3A5uuBw7-champion-subclass-list, we could see Riot's subclasses, one of which are Juggeranuts:

Nasus Darius Mordekaiser Illaoi Trundle Olaf Garen Shyvana Udyr Dr. Mundo Volibear Yorick

Out of all these champions, does the most dmg by far (out which late game it is 1000 true dmg pentakill dunks), has integrated 25% armor pen from level 5 E (Apprehend), plus the most multi target armor pen by only landing one auto or a spell with (up to 30% for 6 seconds), ALL THE WHILE HAVING AOE PULL. So he is able to use Courage of the Colossus, and still doesn't lack mobility since provides that too, so he honestly it's any more kiteable than any mentioned champion. One could argue that he is less tanky than other fellow Juggernaut, however with multi target Qs late game he heals insane amounts of HP. I honestly don't know if he lacks anything really, and it certainly shows in high elo stats :

With 2nd highest play rate in high elo, I can't even imagine any other Juggernaut performing even remotely as well in low elo. Riot explains balancing champions to be good in either low or high elo, however is an exception. Unless Riot intends to buff all the Juggernauts until they reach the same play/win rate across all elos, I suggest nerfing this braindead no mechanics unstoppable kill machine.

I'm a Diamond top laner just for reference.
