Depends, if you make it Range 1 it probably accomplishes quite a lot, and would actually reward creative flying if you could 'chain' your Range 1 bubbles across the table.
My suggestion was to add the word 'unstressed' between 'other' and 'friendly' which doesn't immediately do much to change the way the upgrade functions but makes stress more of a weakness. I believe Attani Mindlink was intended to be balanced with stress as the weakness (much like Zuckuss) when in fact Mindlink lists are more resilient to stress, not less resilient.
Range 1 would be interesting. 1-2 would probably be balanced, and 1-3 would be fine, but none of that makes much difference to Jumps which IME usually slow roll around close together anyway. I've rarely seen a torpscout list which flew its ships far apart unless it was forced to by good turn 0 play.
I disagree about MIndlink's intent. I think it was meant to encourage a different style of flying - using swarms that fly far apart from each other, encouraging flanking and k turning more than PTL whilst still giving similar benefits, and encouraging large numbers of smaller elite ships to hit the field. Enough so that my proposed change to it before it started being used on Torpscouts was to limit it to one focus token and one stress token, because a large part of peoples' concern with it seemed to be the way it enabled token stacking on Fenn/Assaj. I wanted to enhance the stress protection aspect and limit the focus stacking aspect. Its use on Torpscouts changed my mind on that though.
My evidence? I've run a list like that for several months and it's really interesting and really challenging and *really* fun when it goes right. I'm really looking forward to bringing it back to life with Inaldra and Genesis Red. Making Mindlink only work on unstressed ships kills that archetype entirely because you could never pass an action to the K turning ship, and you could only get your focus action with the last ship to move which would make it almost impossible to run.
But of course, without being the designers, it's impossible to know for sure what they intended. I'm more than prepared to accept that they might have intended the stress-passing as a penalty.
