an idea for vision changes

let's be honest, nobody really likes the changes to vision that were added in the preseason. pink wards are taken out too quickly meaning you can't really ward defensively, sightstone was nerfed, and yellow trinket is on a ridiculous cooldown. blue trinket is your best option right now, and riot plans on nerfing it for reasons I will never understand. not sure why everyone thinks vision is "op". but let's get to the point

what if stealth wards were brought back, but changed? my suggestion is that they be visible like vision wards, but untargetable. you will be able to see where the enemy is warding, and learn their warding habits, much like the symbol left behind after a yellow trinket falls.

of course, if stealth wards were completely untargetable and could never be taken out that would be op. it only makes sense that revealing them with a red trinket, wraith smite, or vision ward would make them targetable again so you can take them out.

thoughts? (I hope this makes sense it's 3 am)
