The Devs apparently learned very little from the bad aspects of Eureka.

I think that person meant that 24 and 48 man bosses are limited in practice when there are only 1-5 people in the instance later on like in Eureka.

... This makes no sense. Why do people here keep trying to push the narrative that Eureka is a ghost town?

1- Eureka is still very active. Just recently I popped into the 3rd zone to hop in an NM party, did 2 and popped out ... then went to a fresh 4th zone and helped spawn 2 nms with people so that I could get the rest of the Crystals I needed to complete a glam item. People still do BA runs. Much like anything old it's prob not on the top of most people's list when there's NEW content but in down time it get's busy.

2- This is ALSO taking the place of this expac's "deep dungeon" in that you can go there, use an under leveled job, play it with full skills and gain levels from that (but this time with the benefit of not speed running one shotting everything so you can actually properly play with a job at max and see how it is). If it's anything like PotD or HoH it's likely to be the most effective way to level up to a point.

There's enough information on this to have a decent idea of what it'll entail. You still need to grind mobs to pop stuff, same logos action type mechanics and grinds, etc. etc.

Ever bit of battle content for PvE in this game can be considered the same at it's core. Not sure why anyone would think a battle zone in this game could be that different from a foundational level ...
PoTD/ HoH/ Dungeons/ The Hunt/ 24 men Raids are basically "kill mobs to pop a NM" cause you have to kill small monsters who don't pose much threat alone to get to kill a bigger monster. Trails/ Ex/ Savages are just harder Bosses. The end product is different but the core idea is the same.

The difference comes in how they feel and what you're doing it for.

When I last checked, Pyros, Pagos and Anemos had 6-8 people in each instance. Not the 24 or 48 needed for these new fights.

Let's hope so! I love it when devs think further ahead than 2 months and make content which either scales with the number of players doing it or keeps people playing a long time after it's new.

Everytime I've gone there have been a bunch with a regular BA group running almost daily. This has been on Crystal DC and a friend and I earned WHM relics not too long ago (this character I might add). We have all the Hydatos Eureka gear for healers and hope to do BA one day we're just been busy. Someone I know on Chaos just earned her BA mount although I haven't personally been visiting the zones so I can't comment on numbers but the discord has to be active if she got it this past week.

IDK when you last checked but I legit did that last weekend. Heck, I recently watched Mr. Happy stream himself randomly joining a BA impromptu run and he's not on my DC, maybe you checked at a bad time.

You can count on people doing the most efficient thing to get through the leveling slog. Tis why PoTD and HoH are still going strong even through people ignore the top prizes to repeat the low level stuff for the returns on time invested. If they make it so that you can reasonable try out a job at 80 on mobs that don't die 1/3 through your rotation and make it faster for leveling than dngs then it's gonna be populated forever regardless of loot or relic farms.

Tis why I think they made it lvl 71 to enter. Logically you would need to be 80 to even unlock it ... right? But next Expac you will be able to story skip Shb so you can have a character who is low level but all story done and if they do that that player can use this to get from 71 to 80.

Maybe server differences because on my server, Eureka at peak time is full.
I never played Eureka before and started about a month ago, now at Pyros and it is well-populated.
