its not the fact that it helps give vision, its the fact that it has unlimited charges even after destroying it, it should only be allowed to be used once per round even after its destroyed, and there is no cooldown on it to come back, the fact that it has a 30 second cooldown after its destroyed is actually insane because he can just continue using it with no reward. the ability should be nerfed to at least where you should be able to charge the ability back with 2 kills like raze's E or Jetts E which will act like you earned the camera back even 1 kill at least because vision in This game is the most broken thing
