Very well said. I had not considered sight as invisible power, and the idea that "on a subconcious and instictual level, most players experience it as something that punishes them for not doing something that may or may not give them an advantage" seems true.

We are still left with the problem of making stealth have more counterplay and the vision game a more positive experience. One possible solution is, in my mind, overlays. I think if Riot explored depicting stealth and other vision-denial effects in different ways to the player, they could solve a lot of the issues plague champions like Evelynn, Teemo, Shaco, Rengar, and the others - granting more counterplay to a champion while increasing that champion's outplay possibilities. Another possible solution (something that needs to be done, IMO) is really focus on trinkets and wards, making each unique in it's own way.
