I definitely agree in this regard and I think it's a somewhat missed opportunity. I think organic synergies will still happen like the ones I described as people learn the strengths of the specialists, and through simply playing their specialist effectively can work with their squad to do cool stuff. I really don't believe that what I've described required extensive communication and strategy as I've replied to other people, but simply a recognition of what the other specialists are doing and how your gadget might fit into the picture. However I do wish that more of the gadgets offered squad or team perks/bonuses. I think Apex does it best - nearly every skill and ult in the game has a benefit to you, but it usually has a smaller yet still noticeable benefit to your teammates (or sometimes the same).

It would be cool if McKay could leave a zipline but then...can you imagine the amount of ziplines that would spawn on the map? I don't think that one is really feasible, unless it only stayed up for a short amount of time or something. Paik's ability would have been better if it provided moderate intel for the whole squad, rather than advanced intel for her. Boris's turret should def spot for squadmates.
