No reliance on FATES please. I know there has to be a better way to make accessible open world content that can cater to solos and parties alike.

I'd take a dynamis-ish free for all where you get currency towards relic, with hunt marks scattered all over over grinding fates.

Open world raid might not work considering the emergency missions go about as well as a train wreck on fire while a meteor is crashing down when there's no coordination.
