They may not want to but they need to.
Dedicated cross world spawning linkshells/Discords plus current third party automated tracking and detection relay tools plus level 80 burst damage have significantly changed how the player community hunts. The content has broken down when lack of a third party tool that breaks the ToS means there's a significant chance you won't get to participate in the kill even if you were the one intentionally doing the work needed for the spawn to happen.
I find it hard to believe that SE can be satisfied with the way things are.
SE either needs to incorporate the third party tools into the game so no one who prefers to honor the TOS is at a major disadvantage compared to those who prefer to violate it, or they need to change the content design so the advantage of having those tools is significantly reduced if not eliminated
Give S ranks a 3 minute invulnerability debuff. That gives a spawning party enough time to manually scan a zone for the S rank and travel to its location so they get a chance to kill it alongside the third party tool users who knew exactly where to go the instant it spawned because their tool already knew the location.
Change S ranks so instead of reserving their next spawn location when killed, they will randomly spawn at one of the unoccupied spawn points when all conditions (including the hidden timer) are met then prevent the S rank from being detected from a greater than normal distance. That way the third party tools can't determine the location in advance and their users will be forced to do some actual hunting for a change if they want to kill it before others can arrive.
Reduce the damage being dealt to lower level marks by higher level players in some fashion so at least the S ranks require a little bit of time commitment to kill instead of getting smashed in the space of 2 GCDs. I've posted one idea above; I'm sure there are other ways to get a similar result without having to resort to a level sync.
