Regarding each of your points:
1. People who work might see the call but they'll never make it in time if they're having to travel cross world to get there. S ranks are getting swarmed the moment they're found by pull on sight cross world players now.
2. Coeurl is low pop. You don't need 200 players to kill a S rank so we never struggled with them, thank you very much. Stop making assumptions about what things were like on the low pop servers.
3. Can agree here. If you were in a dungeon or doing something else when the spawn was relayed, there will always be another S rank to catch when you are not occupied.
4. Go back to #1. The potential for more hunts is canceled by the additional transport time involved. Things are dead before you get there.
5. Can agree again here. It has been fun doing Rank A trains with players from other worlds and visiting their worlds in turn to join their trains.
6. SE never said they're going to turn them into FATEs. They stated they were looking into possible solutions and that while FATEs were one thing they had considered, it would be such a major rework of the hunt system that they would be unlikely to do it.
There was some brief cross world drama over Rank As when the servers came up on the 23rd but that died out pretty quick. Since then things have been normal for the Rank As to the best of my knowledge.
The problem is the S ranks, as the hunt community predicted as soon as world visit was announced. SE has allowed isolated problem players to spread outside of the worlds they were confined to and into the entire data center. It has not solved any problems. It has created a larger one.
Sorry, but right now most of the Crystal worlds are getting plagued by a Balmumg S rank hunter that evidently already had a bad rep on Balmung because of his use of a third party program to be alerted to spawns immediately and pull on sight tactics. He even stated in zone shout on Coeurl after one of his pulls that he camps one of the city state Aetherytes then immediately goes to the world with a spawn when his program alerts him, that's it's our tough luck we aren't killing it before he gets there. The drama it is causing across multiple worlds has been ridiculous. Players from other worlds in Crystal were complaining about him in our zone shout at the same time.
Something needs to be done. Making S ranks immune to damage for 5 minutes after spawn would be a big help. Your pull on sight Balmung neighbor could go ahead and pull once the immunity wears off but at least it would give players who rely on linkshell relays instead of unauthorized third party programs a reasonable chance to get there and get their hit on the mark.
