I thought you would have actual interesting questions. You listed everything in the patch notes and asked, "Any thoughts?" Sorry, kind of bummed that I read all of that and found it devoid of substance.
I will comment that no one ever bought Eleisa's miracle and that Akali's changes may turn out to be nerfs. It just made it so you can opt to take any runes you wish. Which, for our purposes, is pretty cool because now you can grab MS quints or MPen quints. The changes do warrant some new builds too.
Also, I think DFG got buffed tbh. 5% less cdr for 200 less gold. Since most builds are so close to max cdr for AP casters, that change is somewhat negligible. Especially for characters like Leblanc who already have short cooldowns.
