Patch 7.9 updates a ton of items yet Athens is still trash.

20% cdr 10% cdr

As I am on mobile, I can't get the specific stats but from the top of my head, ap isn't the stat these two items should be judged by exclusively. After all these are both support items and both have utilities that benefit more the just the owner.

No amount of buffing numbers will make Athene's a good item. It'll NEVER be a good item as long as enchanters aren't allowed to be aggressive, and that's not even considering Redemption/Locket outclassing it by a few good miles.
