IEM shows that Athene's was massively over nerfed.
Pretty much everyone just builds Morellonomicon instead, even against assassins like Fizz. Riot nerfed Athene's because they thought that it limited item diversity. Well now everyone merely builds a different item instead and there is still no diversity in AP item purchases.
Morellonomicon has more regen, more AP, is 600 gold cheaper and has a situationally powerful and underated grievous wounds effect. Meanwhile all Athene's has over Morellonomicon now is a mediocre amount of Magic resist.
I think that the items are currently in a decent spot in terms of stats, with Athene's being a more defensive item and Morellonomicon being a more offensive item. The main problem is that the cost disparity is way too high. To solve this i would suggest slighly reducing the cost of Athenes to 2500 and slightly increasing the cost of Morellonomicon to 2300. This way there might actually be a reasonable choice rather than Morellonomicon automatically being the superior option.
Edit according to lol Wiki Statistical Value
80 ability power = 1740g
100% base mana regeneration = 720g
20% cooldown reduction = 633g
Total Gold Value = 3093g
60 ability power = 1305g 25 magic resist = 500g 50% mana regen = 360g 20% cooldown reduction = 633g Total Gold Value = 2798g (The new Athene's passive is significantly worse than 50% base mana regen so its safe to assume its gold value is roughly around 250g, even with this passive included Morellonomicon's stats have a higher gold value)
Mana Font: Mages average between 1100-1200 Mana at level 18. If you have 0 Mana you gain 18 regen, if you have 50% mana you have 9 regen. The extra 50% base mana regen on Morellonomicon gives you 10 mana regen AT ALL times at level 18.
Morellonomicon is way too gold efficient.
none of the other build paths will be reverting
, and I think Zz'Rot portal is on hold and wont be in this patch
was always massively gold efficient, way before
got nerfed. I think the change in preference has more to do with the changes to mana regen: before Preseason 5, Morellonomicon and Athene's had the same amount of flat mana regen, except AUG also had Mana Font and its regen-on-kill/assist passive. Now Morellonomicon's 100% base mana regen is a buff to its late-game regeneration, whereas AUG's 50% base mana regen and different Mana Font passive makes it a less attractive choice for early game mana sustain.
was practically compulsory to getting an edge in lane. Its MR allowed you to take less poke, and its mana regen allowed you to poke without having to worry too much about mana conservation, so an AP-versus-AP mid lane tended to be an arms race where the first one to get a Chalice could out-perform their opponent on every level. Grail exacerbated those issues by letting the wielder cast stronger spells a lot more frequently, all while mitigating the enemy's magic damage. Making Grail the dominant pick again would just reinstate the arms race, whereas the build path for Morellonomicon doesn't immediately solve the wielder's mana issues, nor does it guarantee defense against the enemy's damage.
used to give 8 flat mana regen. To give that same amount now, your champion would have to be between level 9 and 13, and Idol is usually a component you get before that. I agree that Mana Font isn't particularly strong, but then again I don't think it should be. When Mana Font is sufficiently strong on its own, particularly in the early game, it just means your champion doesn't have to worry about mana problems at all. It's a remnant from a time where item-based mana regen didn't scale into either the early or late game, where it was the only item capable of increasing your mana regen as you leveled up. Now that mana regen got reworked, its effect is redundant.
