Tesla needs 2 rings like the Mortar

I read on the Wiki more than a year ago that the Tesla has a trigger range of 6 and an attack range of 7. I believe there should be both circles for the trigger and attack because it assists with tactical placement strategy. Yes it is only a 1 tile difference but still visually it makes it easier to see where these two boundaries are at.

I included a picture, I have no photoshop experience so please excuse the drawing, you get the gist of it.
