Not necessarily. 40% is not always going to be greater than 45, especially if you pick up arpen masteries and runes, since the % is factored after the flat. That aside, Black Cleaver actually shreds the armor, not just penetrates, so your entire team gets use out of it. Your bruisers that aren't building any arpen are going to be doing more damage as a result. And getting the 3 stacks on whoever is the focus shouldn't be difficult to do, so don't even try to say that's detrimental.
