Great item idea

I was thinking of how there aren't many hybrid items as I would like to see in the game and how sometimes it would just be nice to have a 1 stat boost without having to spend a lot of gold for an item with 3 stats when i'm only looking for a specific stat.

So I came up with a idea to implement rings into the game. You could make them a slot specific item like the free wards. Have 2 slots for rings and each ring you buy would give you a flat stat of your choosing. Examples below.

500g ea Ring of might - 40 AD Ring of life - 300 HP Ring of swiftness - 10 MS Ring of sorcery - 50 AP Ring of fury - 25% AS Ring of piercing - 25 ArmP

The numbers and price are obviously up for debate and there would be other rings for other stats, these are just a few examples.
