I don't see that as a problem. They just need to add the ability selection all or a few squad members. However, mostly I didn't have any problems with the chain. Quite a classic system, as in poe, even seems inconvenient to me. Also my companions for the most part avoided the "dangerous" places, not counting the traps, because the traps need to be detected.
For me, the main problem is stealth. I'm tired of sending each character to stealth, the same as it was with jumps, well, they sort of solved the problem with jumps.
So the chain itself can not be removed, they just need to add the ability to select.
