Why not rebalance Archangel's?
Let's be honest this item has heavily fallen out of popularity, it doesn't fit most builds and doesn't fit the build that you would think wants it most (low cooldown high damage mages)
Only a very few amount of champions even bother building it, so how about you rebalance it slightly
Reduce the amount of AP it provides from 60 to 50, but increase the % from 3 to 4
The core item itself would not change from 60+30 AP to 50+40 AP, however it would scale much better with other mana items as well as your champions base mana
Most champions having around 1k mana at 18 this would give most champions that build this an additional 10 AP
Also champions that happen to build mana in their items would find another 5 AP every 500 mana


and sometimes
or not (though, the shield is not that great, so that may already be the case); otherwise, it would need to have the stack time adjusted to not favor low cool down champions so heavily in terms of how quickly it can be stacked.
