Thanks for taking the time of making a graph for ilustrate the argument, still people is literally missunderstanding so many things.
The point of making the skill toogle was not only because it was horrible and missleading, also with the new light we couldnt activate the effect on the Anatomica, it was for Mirage to be actually usefull with her playstile besides nuke sanctuary.
For those that thinks its the same as X warframes, you need to remember something very important, tose warframes has some other tools on their kits that syngerizes with them and having better stats (Like having quite a lot of armor, overguard, high base health, armor strip, etc). Mirage is a Glass Cannon with only synergy on 2 skills... SO, if you remove the strong part of the frame (yeah the clones NEEDs the eclipse) its a worse mistake than the Chroma case.
Now, if the argument is because the Helminth, the line of thinking is: "yeah who cares about mirage, the skill we can get its the important part, she can die on the corner".
ITs not a team buff (Because the augment is on when youre literally hughing your teamates... like please think that more), Its the core of the always used build for content outside sanctuary.
