@Meddler the best buff you could give to Darius right now is to fix his bleed bug to do its full dmg
This has been a known issue since his release, he doesn't do the full damage on his bleed or he does it completely inconsistently.

Edit: The reason I have been spamming these types of threads lately is because there is no known way to know that Riot is acknowledging and working on fixing this without them directly talk about a fix coming soon.
A season 3 Quinn main who lost his sh*t when Lucian was released.
