Okay. Sure. Winrate isn't always 100% reliable, since it doesn't tell the bigger picture. But just like a champion with a huge winrate still shows a problem, one with a fucking 47% average winrate shows the champion is clearly not OP. Winrate might not be ideal, but it still gives a pretty fucking good idea of strength, and, I'm sorry, but you cannot legitimately claim that a 47% average soloQ champion with a 50% proplay winrate is OP, especially when nothing they do warps the meta in any way.
And, sure, the bleed isn't a steroid. But it has the exact same number of effects as her passive and all are beneficial to Darius. Are you really going to argue his passive isn't the same tier as hers because his fucking bleed is a debuff to the opponent while hers gives her a damage boost? That's fucking nonsensical, since it's still a fucking benefit to him either way. You're just fucking arguing semantics at that point. Argue the strength of the passives or whatever, but at least make an actual fucking argument rather than "lel bleed not buff it debuff hurr durr"
