Tear of the Goddess change ?!?

Tear of the Goddess

Mana Regeneration: 25% --> 0% Additional Passive - Awe: Refunds 25% of Mana spent Tear of the Goddess has always been the go to spot for a ludicrous mana pool. However, paradoxically - it also favors very low cost spells in order to stack it up. This iteration swaps out the minor regeneration for a very powerful effective mana cost reduction for truly painful spells.

The Awe passive is kept on every Tear of the Goddess upgrade. Because the mana is refunded - Catalyst's passive will still act at full power.

Given the context (moving tear away from ability spam) I think this change makes little sense. A lissandra-like passive would be much better:

"Additional Passive - Awe: Refunds 70% of mana spent if your ability hits a champion (8 second cooldown)"

This change would allow champions that have higher mana costs to utilise this item better. While we are at it I think it would also be good to change the other passive to work only when hitting an enemy (monster, minion or champion) to prevent cheesy stacking of mana with skill shots while walking from base.
