Next season New item. Deeper game complexity: Negawards

I have an amazing idea, (such as you've heard 1000 times) for new items and game play depth for the next season. The idea itself is simple, but if implemented would have revolutionary effects on in game strategy that is both simple, and complex in it's nature.

Negawards. A new set of wards and trinkets that would revolutionize vision control and make it amazingly more strategic. Basically similar in nature to the wards and trinkets already established, negawards would provide an entirely new perspective and mechanic to the vision control game.

I can see it working thus: Like normal wards, there would be greens and pink, but both would be much more expensive, and the limit on such wards would be even more strict than the limit on normal wards, perhaps 1 of each type. The negawards would work in much the same fashion as normal wards, however instead of providing vision, they would negate the vision of normal wards. The idea is that you would be able to deny vision in an area equivalent to a normal ward. The pinks would only reveal green negawards.

I think this is a simple idea that truly has the potential to add extreme depth and complexity to the game, without stranding lower elo players in a zone where the effects have no difference on game impact.
