It is entirely necessary that the enemy is told that they are revealed - enemies need to be able to react to the fact that they are visible. Just like Paranoia and Destiny, the fact it reveals EVERYONE will help disguise who is in danger. That said, I honestly don't see this Clairvoyance being used for scouting - this Clairvoyance will be used for in-fight sight (such as chasing people through brush).

Counter jungling really doesn't take that long and, if necessary, just add a "Clairvoyance cannot be activated during the first 120 seconds of the game." so that level-1 invasions aren't spoiled.
