yep, Last Whisper is a problem too. Unless you're an outlier like Corki or Kog'Maw where you do enough magic damage to make it non-essential, it's pretty much essential on every champion. There's no option there.
I think removing items that have an active component that are non-mandatory instead of changing it is a bad move and only homogenises item builds further both in terms of options and in terms of gameplay. We need more actives and less stat sticks.
edit:
here's their context post
"basically Leblanc and Ahri are kinda broken with DFG so instead of fixing their gameplay issues we're going to remove an interesting item that is generally healthy on other champions
oh and we're buffing Ahri. Maybe Veigar at some point we don't know."
zzzzzz
