I just had a massive brainwave for a support item
essentially it'd be the support's bork. healing and shields gets increased based on a % of an ally's max health. not a flat add on, but stronger heals and shields will benefit more from this. also to stop it from being a must buy on soraka the % decreases as it's used, and builds back up after a time spent not healing.
how's that sound? too close to the new athene's?
With these in the items, I don't think we'd need that. Also, you have to remember that supports want strong base buffs on their heals and shields, or items that use the supports health pool instead, like
. The reason for this is because marksmen have a low hp pool, making the item inefficient on them if it uses percentage like
.
