Please remember that there are THREE new upcoming bruiser/fighter items being added as well.
Which will allow champions like darius and garen to safely build MUCH more AD. Sure, garen's judgement does 25% less damage when hitting multiple targets, but the scaling on it seems overall higher and riot says they expect him to safely be able to build 250AD or so with the new bruiser items.
Nobody is mentioning this, but when you look at the new reworks, you absolutely have to look at them ALONG WITH the new items, because the reworks were balanced around these new items.
