Future Eureka?

Originally I was leaning positive on Eureka. The first stages for relic weapons were always grind fates or something in world. However, in an instance filled by the data center it would probably have better population numbers than being restricted to your own world. However, a thought entered my mind about the sustainability of Eureka's content. When the patch that fixed Pagos trains dropped, population ( at least on primal ) in Anemos plummeted and I suspect this will exponentially increase upon the next leg of Eureka. Thats only the tip of the iceberg though.. what about during the next expansion. More than likely the numbers for Eureka would drop further.. and further still two expansions down the line. At least with the older Relic and Anima weapons you were tasked with doing trials and other content that can be unsynced or pooled with people doing the content in roulette. Is it possible Eureka will be unsynced? Still.. just the idea of sitting in an Eureka instance alone, unsynced, killing mobs just feels gross as the only way of progression a year or two down the line.

TLDR; Eureka will be dead in 2 years. Unsync mob farm?

It'll probably end up soloable like turn ins for items like how they have the pazuzu feather one and stuff like the pagos crystals nerfed, removed or a reverse turn-in (frosted shatter to pagos, etc). The light rate will probably be adjusted so you get a decent amount by yourself on mild difficulty mobs I guess or make you OP by being max elvl in Anemos with no sync where you would be hitting for hundreds of thousands per hit. Not much different from the zodiac/anima grinds really where you can do the bulk of it or all of it unsync by yourself. They could always drop the grouping penalties so anyone else that is there can just jump into your party and do it no matter their elvl.

Anyways, if the relic armor coming later requires the older stuff it will get people into Anemos again. People starting new weapons need to go back, too.
