Old Morellonomicon on ARAM

Can we please have the old Morellonomicon (or a similar item affet) back for ARAM?

Given the way the mode works (constant use of spells/abilities is required), the fact that you can't just back and heal up and restore mana, mana pots are no longer a thing outside of lucky Klepto procs, and the reduced regeneration aura of the map. Maintaining any level of usable mana for extended periods is virtually impossible even if you have the new Tear/AA/Seraphs.

Even taking Manaflow Band rune isn't enough given it's extremely long cd (relative to the timeframes given in the average ARAM game).

Morellonomicon solved this problem for mana using mages, thanks to the fact that teamfighting is a constant thing on ARAM. But after the item changes there's not really a work around. Even managing mana and using abilities sparingly doesn't help because, again due to the nature of the game mode, you're going to be casting often.
