Can we buff/change black cleaver please? Or nerf trinity a bit?

It is insane to me that even a champion like Sett is seeing higher winrates going trinity force, which is 700 gold more, over an item that is designed for him that is Black Cleaver.

Black Cleaver was made to be what every AD melee/bruiser would want. To shred armor, deal more damage with physical damage skills, and move faster.

However, trinity just deals more damage, even with one sheen proc, as no one builds armor and Black cleaver has lots so much gold value over the years. It went from 30% armor shred to 24% armor shred and saw no adjustment to the gold price. Why was this done? Was it just because lucien was abusing it? That's all I remember when they nerfed this item.

Why not make black cleaver melee only, and give it something more, maybe a new effect and a bit more gold, but just something to make it better.

It is shocking that champions that don't even have mana or can barely proc it that often, such as Sett/Garen, are benefitting from this item more than a black cleaver would. To me, this is a huge balance issue and shows the lack of item diversity and that perhaps trinity force is overtuned.
