Bring back Mana Manipulator?

It wasn't that good an item. It only cost 300 Gold. But it was better - healthier - than Essence Reaver in my opinion.
So maybe Riot could bring back a similar item again? I do have some suggestions :)

##Mana Manipulator

• Recipe: Amplifying Tomb + Faerie Charm + 135 Gold = 750 Gold

• 30 Ability Power
• UNIQUE Aura - Mana Warp: Grants nearby allies +25% base Mana Regen per 5 seconds.

It grants Ability Power and Mana Regen for allies while costing little Gold.
For the Support it's worth 832.5 Gold alone, which is already Gold efficient, but it also gains 180 Gold in worth per nearby ally with Mana.
Supports couldn't buy it immediately. After getting their Gold item and Sightstone on their first back (is Sightstone even still a thing?) and then maybe boots and upgrading their Gold item and getting something useful like Mikael's Crucible, they may be able to buy it. But if their Marksmen is someone like Ezreal or simply likes to spend Mana, then they could earlier just as well.

##Frost Queen's Claim

• Recipe: Frostfang + Mana Manipulator + 485 Gold = 2100 Gold

• 40 Ability Power
• 2 Gold per 10 seconds
• 50% base Mana Regen per 5 seconds
• UNIQUE Passive - Tribute: [...]
• UNIQUE Aura - Mana Manipulator: Grants nearby allies +50% base Mana Regen per 5 seconds and +10 Ability Power.
• UNIQUE Active: Fires an ice lance [...]

Many a Support who picks up Spellthief's Edge will upgrade it to Frostfang and then stop. I've seen Supports (myself included) rather sell Frostfang in the late game then ever upgrade it to Frost Queen's Claim. It simply isn't worth it for them.
But with this Aura, it might be a bit more enticing. The changes are:

• 10% Cooldown Reduction
• + Aura that grants allies +50% base Mana Regen per 5 seconds and +10 Ability Power
  • + 50% base Mana Regen for yourself as well
• Cost lowered by 100 Gold

10 Ability Power might not be much - it will certainly be invisible power - but it's something. And along with 50% base Mana Regen, which can be up to 12 Mana Regen per 5 seconds (Jinx), it certainly is a useful aura. And to me it's worth losing 10% Cooldown Reduction. Supports have far too much Cooldown Reduction anyways. Most games I get 45 or 50%.

##Morellonomicon

• Recipe: Fiendish Codex + Mana Manipulator + 730 Gold = 2300 Gold

• 80 Ability Power
• 10% Cooldown Reduction
• 50% base Mana Regen per 5 seconds
• UNIQUE Aura - Mana Manipulator: Grants nearby allies +50% base Mana Regen per 5 seconds.
• UNIQUE Passive: Dealing magic damage [...]

Lastly, I would build Mana Manipulator into Morellonomicon as it A) differs it further from Athene's Unholy Grail and B) makes the item more enticing to Supports.

That's all. Thanks for reading.
