S-Rank mobs needs a invulnerability buff on S-RANKs

[KageTokage]

Hunts are world bosses they belong to no one end of story. Only one change is needed and that is for s ranks to spawn once a week at random with zero player intervention.

S ranks having spawn conditions is one of things that makes them engaging for some people (Namely, that small part of playerbase who actually bothers spawning them) so...no thanks.

I would like them to tone down the number of monotonous kill count S ranks, though, because those are not fun to spawn.
