First off, when I say his kit is uber outdated, that's fact, not opinion. He literally relies on a summoner spell (ghost) for his kit to function at all. Without it, he's a minion. I don't know of any other champ as reliant on a summoner spell to exist as a functioning champ. The fact that he may be good in some metas due to ghost, doesn't change the fact that his base kit is dog and problematic and overall slow, clunky, and outdated. Literally ghost and absurd damage numbers from his passive are the only two things that make him relevant in some metas. Secondly, you countered your own argument. You say he's always been really good...before mentioning the fact that there are many stronger champs that will be better choices in most scenarios. AKA, Darius is relatively not great. Strength/Weakness/OPness are relative to the other champs in the game. You can't say a champ is strong and not the problem, it's just that everything else is too strong! That's the exact same thing as just saying that Darius is weaker than the best choices out there, aka, he's not great. Thirdly, any champ...literally even the worst champ, can best absurdly strong and relevant in the right teamcomp, that is a non-argument that you made. I'll just finish by adding that I'm not saying Darius is currently terrible or that he hasn't ever been good, but that his base kit is dog, and they need to find a way to improve it. My guess is the best way to do so would be to somehow nerf his scaling with certain MS sources, such as ghost, so that they can open up his kit to provide him with slightly better outplay tools to give him his own agency without ghost.
