Darius is in really bad spot right now
Seriously we do not ask that much. At least take a look already! You were nerfing the guy just by requests of lower tier players. Yeah I understand they are majority of community but this isn't how you balance the game. (This damn majority is already down voting :D ) The thing is really simple. Some people ask speed up bonus on his R, some ask higher attack speed. For some reason people decided that his core weaknesses are the reason why he perform that badly. The main reason is just simple stat-checking that coming from everyone around including tanks/adcs/supports. I swear God that happened to me so many times when people just disrespect my passive and bleed stack facetanking me to the death while being behind/equal. Once again. Take a damn look at his Q blade width. It's too small. No. I'm perfectly fine with this when you just trying to get some sweet stacks. It takes skill to hit it, you play your mini-game achieving small task to win duel-teamfight. But when it comes to actually chop people in half you will probably miss damn Q. Suggestion is so simple. Increase Q width to pre-nerf state only during passive being fully stacked.
Small reminder that Riots nerfed the guy even before they actually released new adcs itemization and their rework, apcs rework and their items, before this game became like "protect adc with solid sup items
and solid tank-sup items
. Do you really think these nerfs are relevant? Not even asking to revert them but give us some of the powers back in more specific way.
