Are there any mid laners that buy Athene's anymore?

I'm wondering if Athene's is better than Morellonomicon on any mid laner now. Is there a point to it existing in the game at all now aside from tricking people who haven't played in awhile into buying it? If you're going to make it strictly worse than nomcon then why have it at all? I don't see how making nomcon slightly more expensive changes anything. Athene's mana regen doesn't even work the same way anymore. It was good on certain champions because it encouraged them to use their mana more to keep it low so the mana regen was higher.

As an Anivia/Xerath main. I don't understand what Athene's niche is supposed to be anymore. These champions were the poster children of Athene's rush champions, and I can't even justify buying it on them anymore.
