Darius's playstyle is too mentally draining to win with

Before you start downvoting and hating. His playstyle is too mentally draining to win with at higher divisions. Numbers look strong on paper but downsides are too huge to actually make that worth. Id rather get rid of numbers in exchange for reliable tools/some utility.

What defines Darius? For me its fancy R chain in teamfight when people literally scream in chat "DUNK DUNK DUNK!". Really awesome moments. I guess this is the only reason why I keep maining him for such long time. The rest stuff is kinda meh. Well sometimes it is satisfying to hit 3 people with ur blade at low HP but... But this isn't reliable and it gives people extra reason to cry about 36% missing HP heal as a proof of their point about Darius OPness. If only Riots could take a look at him again after 2 years of juggernaut state (Give some better mechanics to make him less frustrating/gimmick)

P.S It doesnt mean I want this champ to get buffed. No. Seriously he's not Mordekaiser or Ryze that nearly impossible to balance without killing entire concept.
