Expanded Utility Support Items

They always talk about how supports are meant to have more utility and less AP... (And less gold due to lack of kills and CS)

But what if they created some items that were meant to address that issue while not damaging the balance and making them OP...

How about items that give a LOT of good AP, but that LOSE power when you have lots of kills and a high CS. Additionally, maybe a few masteries that gave VERY nice boosts in several areas, based on having few kills and low CS.

This could allow more supports to have a meaningful impact in game and give a positive shift in the meta.
