I think that Tear of the Goddess is a very fun item thanks to the "mini-game" it brings of using skills to stack mana.
I think it would be cool to have a support upgrade from this item, so that it becomes more common for various utility supports. Something that has some cooldown reduction, less offensive stats and some interesting utility active. This would allow more support players to enjoy the "collect the mana" mini-game, and seems a pretty natural upgrade for Tear of the Goddess.
Any comments are welcome.
