Is sorcery even worth taking anymore?

With the recent removal of Ultimate Hat, it doesn't make sense to me to take the Sorcery tree as a primary. Most champs will benefit more from other keystones than Aery/Comet, and Phase Rush is almost useless on a lot of champs (I guess Ahri could benefit, but she's waaay better with electrocute). Except for support and some special cases, Sorcery seems to offer very little compared to other trees.

Midlane mages used to take Sorcery as a primary all the time, but now it seems like going Domination is just so much better for most mages that aren't utility mages. Now you can pick up electrocute and ultimate hunter. The one thing in my opinion that was holding mages from taking Domination used to be Ultimate Hat, but now that's essentially in Domination.

It's not really worth it to have all 3 options in Sorcery either, as they're mostly just small buffs. It just seems so much better to go Domination on most champs that used to take Sorcery.

Thoughts?
