Why does hunt mob HP not scale?

[Alberel]

most of the game you talk about use this sort of feature (world boss) to a minimum. without forget you barely have as much people wanting to do them. here because of the instance they have reduce the number of people that try to kill the Rank S and A but in the past the number of people was excedding the 200+...

we can talk of world boss for hours, like at the start of WoW where you had a rush for the first group to get Kazzak and the 2 minutes of fight... no seriously, this system is more and more abandonned in other game they leave them, but they are often relic of the past for nostalgia that drop garbage then not a lot of people are interested in them.

I really don't understand what you're trying to argue here. More players fighting a hunt target means more damage to said target. If the mob's HP scales based on the number of players actively fighting it the time it takes to die should roughly be the same no matter how many people are present.

What exactly do you think is wrong with this? Other games use this exact mechanic and it works. If WoW's open world fights are abandoned then that's on Blizzard, it is totally irrelevant here where the hunts are so overpopulated that people are raging at each other whenever someone pulls.
