Making pink wards visible, but with infinite duration, is a brilliant design Riot!

In my opinion, I think Riot touched on something brilliant when they made pink ward visible but with infinite duration.

They made the Vision Ward feel powerful and unique. It grants true sight - a rare effect in League - and it can potentially last forever, giving you so much information over it's lifespan that the '1 per player' rule doesn't even feel limiting.

Riot's use of a 1 Ward per player rule is great too. It means that there will be less vision (less info) on the enemies movements. We can't have all of our flanks covered.

The real genius though, IMO, was that they used the attributes of the ward as levers for power. If Riot where to revisit wards, maybe they could use the attributes fundamental to wards - their duration, their health, their field of sight - to give us some interesting vision options.

Basically, I think that if Riot were to give us a variety of wards, each with a unique function or special, people might be inclined to ward more, and enjoy playing around with vision.

There was for a time an item on the PBE called the 'mandrake ward' which gave no vision, but alerted you with a ping whenever an enemy came within it's range. Here again is Riot playing with the functionality of wards. Oddly, nothing ever came of the mandrake ward, despite it too being a very interesting design space.

Why don't we see more of variety when it comes to vision? The game has a huge variety of spells and items, and even though there are many similar effects - there are 5 spell-shield effects, for example - all are different. Why doesn't Riot apply more of this design philosophy to sight, stealth, detection, and denial?

Part of what makes this game so exciting is all the unique items, all the unique abilities. Why not have wards that each have a special ability?

Here's a fancy mockup of what I'm talking about, with more detail: Ward Variety & Sight Options

Would you buy these? How would you use them? How would you outplay them?

Seriously, we need to get Riot and the LoL community to have a serious discussion about vision!
