Can Thresh have aRange Indicator for his passive?

Hi Riot, I wanted to throw an idea out here to see if its possible. The Idea im having is to give thresh a passive indicator. I propose this change because it may be useful to thresh players. Its useful because this can seperate good thresh players from great players. I say this because when if thresh roams to any lane a ghost will appear letting the enemy know that thresh is in the area and thresh himself may not know this , if he has a locked camera and isnt looking at the lane he is roaming to. But what if thresh players knew the range of there passive, perhaps these players could use there range to make it seem there not in there area and when the time is right strike. In other words greeat thresh players would know when to roam and how to roam thanks to them knowing how big the passive area actually is. However i dont know if this is even a good idea its an idea that came to mind and hopefully can bring up discussion on thresh's passive. Please and thank you for listening/reading
