For the GC quests:

I wonder if it would help if the GC quests were altered to award seals to everyone in the party at the time the player with the quest flagged completes the objective.

This is a problem carried over from 11. If you didnt subscribe at the time of an update, it was hell finding a party to do quests/missions for example.


I also wonder if a better solution would be to place certain quests on their own questlines outside of main storylines, flaggable with no or few prerequisites. So even if the higher up people cant be bothered to help, at least the lowbies could offer to help (as there would be no pre-req quests, you would literrally just have to be a certain level). That way you can continuously shuffle people into new areas/new content hassle free and then the main storyline can be experienced leisurely as the sugar coating on the top.

For the AF quests:
Hmm, similar, maybe function it like a leve quest with item/xp/gil/seal rewards. ;/
