Let the 'Eye' sightstone trio use whatever is our active trinket.

So a lot of what I'm seeing is "need more sight! Give us back our wards Rito pls!" Obviously they won't, so how about this.

Remember these beauties? Well how about we have it so that the they take on the effect of of our purchased trinket? My personal issues with these items isn't necessarily their value, but with how bland they feel. Yay. A ward. No, no special efffect. Just, y'know. A ward.

But now let's use the equipped trinket instead.
"Hey support can you scout the area?"
"Can do! drops 4 blue wards in key spots in his area of the map "Wow! You're awesome! Have my children!"

Alternatively, Just turn into a ward genocide, able to spam Oracle Alteration and run around the map creating a blackzone.

Now, let's look at fringe abuse cases. More specifically, standing at your nexus with blue ward equipped. Blue ward has no limit to how many can be dropped (which I think is insane but whatever,) So your side of the map is now filled with so many blue wards that you can't even see the ground.

EASY FIX! Just adjust the items, make them similar to teemo's mushrooms. They don't refill at the shop anymore, but instead fill at a CDR that reduces with level, for the sake of this wall of text let's say it mimics the trinket being used. Hell, you could even quicken the recharge rate when the user is dead, giving that much sought after 'comeback mechanic' that riot talks about.

So there you have it, one thought process in one lunchbreak.
