"But the simple addition of this new attribute may need some balancing issues to be covered before implementing it, since it would change how many AP-reliant Supports will have to work with certain items, since some items will become not viable for them. "

Well, there could be an item with a active effect similar to FF XIV's Cleric Stance: it would swap the amounts of Spirit and (but that would require 1 Spirit to be worth 20~25 instead of 62). That way, mage supports would have a tool to deal damage at the right moment while still building Spirit for utility's sake.

That said, I approve of the concept of having a stat that specifically boosts utility like healing, shields and CC. It is so counterintuitive to build utility items and your utility doesn't scale as well as it would with full items.
