I use it also every now and then but only to troll a bit cos it feels close to useless, especially in pubs
as someone who gets a lot of kills every game and tends to rush fights (which imo path should be played for, but to each their own ofcourse) I don't even wanna waste the way too long scan which another champion can just do with their drone which is actually also instant rather than taking 3 seconds which forces you to stand still only to get a free kraber shot in the head.
While it might be somewhat usable for ranked, other champions have this option now too + also their own old passive, so basically he doesn't really have a passive.
Look at bloodhound for example, can track, can ping tracks for team which gives a lot of information, those are actually useful in a fight, wraith passive tells you when you're being aimed at, gibby has an arm shield which stops 50 dmg.
Like i said, compared to other champions his passive basically does nothing and has no contribution to actual fights like other legends.
I have over 15k kills on path and i gotta say i maybe scan that thing once every 100 games just to get my ult back up in very rare occasions, cos you're most of the time just better off rotating urself rather than scanning that beacon which only makes you vulnerable. besides its actually about as fast to rotate yourself rather than scan it.
anyhow i wasn't here to discuss wether he needs one or not, how controversial it may be, respawn had actually announced before that they were gonna work on a new passive in the future (which they said over a year ago) and i was just looking if anyone has any information on this matter.
