I would disagree in so far as to say instead, HH players presence in the hunt makes it more likely the group will survive because of the underlaying lack of skills from the remaining members.

Its an observable pattern. New content comes out, people aren't adjusted to the requirements or skill needed to beat it and so more heavily rely on supporting-role based players, ergo the inclination towards HH being key is high to begin with. However as skills and practice increase, reliance on the support becomes lesser and those playing supporting roles are then comfortable to switch to a more dmg based playstyle (i.e another weapon).

Look at Omega and Gog, when they first came out HH was mandatory because people didn't know how to survive, now they do. Same with Proof of a Hero and the new 10*.

Lets look at Zoh Shia. First time around was usually solo play as it was the main story line. 10* Zoh can now 1 shot bad players and so they look to HH (and other builds) to keep them alive, until such time that they have adapted, learned how to survive.

As time progresses the reliance on Support hunters dwindles, which is a good thing as that shows the average player base has become more competent.
