@Meddler, Statikk or anyone in the Balance team
I (a Darius player who's currently in Platinum) consider Darius to have two more items that are actual reasons for him to be concidered overpowered, but don't shine through as much in the discussion.
The first thing is the current base damage on Decimate. After the hotfix buff, Darius' short trades have become way more potent (...again) and are actually an easy way of bullying most opponents out of lane, especially if those rely on long trades themeselves, in which Darius stomps them even more. His dominance in short trades makes him an ideal lane bully again, even without the use of Bloodrage and his amplified 175 attack range(and this IS worth noting!), and that's too much for a character who brings so much raw mid-game power now.
The second thing I noticed is how much damage the passive does in Bloodrage currently. It doesn't feel skillful to see half of their ADC's HP to simply bleed away after you hit your Decimate but lost reach. In early lane, when your enemy is foolish enough to let you proc Bloodrage, it's not all that extreme, but still, it has lead to a lot of "First Blood"s for me due to my opponent underestimating not only my bonus ad (that part's fine), but also the damage he suffers per second. Currently the ratio of 5 stacks (->Bloodrage, solid bonus AD) is 150% bonus ad over 5 seconds (30% per second EDIT: oops, only triggers 4 times in intervals of 1.25 seconds after the rework -> 37,5% per tick). Combined with the armor reduction from Black Cleaver and some flat armPen from any source, the bleeding frequently deals up to 600 damage as a DoT debuff in the later game. As said, painful to watch, even for me, the Darius player.
I'm not all to sure about the healing on a 3 sec CD with max CDR (even though the heal itself should be really here to stay, you can outplay Darius, playing around Decimates functionality), but cutting the damage buff of the hotfix in half (30/50/70/110/130 from 40/70/100/130/160) and reducing the ratio on Bloodrage'd Hemorrhage (say 120% from 150% total, 24% from 30% per second 30% from 37,5% per tick) would remove some unnecessary strenghts he has, which are leading to really easy bullying in lane and too much colateral damage in team fights (while effectively applying an armor reduction debuff aswell with Black Cleaver, making your ADC die of laughter).
Another reason for the peviously immobile champions to rise is Dead Man's Plate's insane MS-steroid (It's basically a better version of mobility boots, as the MS does not fall off completely when simply taking damage or getting hit by anything). But I don't think it's this discussion's purpose to treat that.

What do you think of these suggestions?
