If you give it to everyone it is not a buff to those that need it, look at what happened with BFT. There were casters that needed BFT to be viable, and there was others that did not. Everyone was able to get BFT, but did that prompt the rise of new casters entering the scene or did it just promote the only strong ones from good to god tier? And let us not forget that it was not just casters that could get the item, AD Malz and Urgot among others gained thrived when BFT was added. More so than any of the casters the item was meant for.
I really shouldn't have to be explaining this, since the same thing is happening once again with the Black Cleaver.
