Hunts are meant to be able to be attacked and killed as soon as you see them. An invulnerability window would contradict that.

What is hindering you to try to spawn S ranks whenever you have the time to do it? Dedicating time to the Hunt is actually what people do who like to hunt. There are people who raid or run dungeons all day long and there are people who hunt or try to spawn S ranks all day long because they like it.

I myself liked to hunt or much more to find the A ranks whenever it was possible for them to spawn again. The sooner they will be found and killed the sooner they will spawn again and therfore the more A ranks you can get. But since Shadowbringers or late Stormblood people are willing do kill them just every 6 to 8 hours with their trains, if at all. Within 8 hours an A rank could almost spawn twice.

It feels like many people don't want to hunt but instead are rather moaning that they have to interrupt their current activity (again) for doing hunts.
