Was the Darius nerfs a bit too much?

I main darius at a diamond 5 to diamond 3 ranked level and im feeling the nerfs on my favorite champion. Not only was his passive nerfed by 10 AD at earlier levels but the handle on his Q now deals only 35% damage aswell, but on top of those they also nerfed darius's favorite/most used mastery, courage of the colossus, aswell as nerfing a popular and my favorite summoner spell for Darius, ghost. My Darius playstyle was nerfed in 4 different ways, 2 abilites were nerfed, 1 mastery, and 1 summoner spell. I just feel like he was nerfed a bit too hard and I feel the nerfs were targeted for low elo where players don't know how to deal with a darius as much and is why he is commonly banned in lower elo but almost never banned in the higher elo that I play in, because experienced players understand his greatest weaknesses, which is being ganked, being kited/cced/focus fired in teamfights, and to deny him 5 stacks of bleed on any champion. I think his winrate used to be around 52-54% according to certain sources? not 100% sure on this, but after checking right now his winrate is below 50% on some sources, 49.83% on champion.gg, 50.8 on lolking, etc.
