CEs are trial bosses but that's fair.
Fragment/cluster farming is what again? Farming mobs?
Leveling raids? Which? DLL, DR and Dalriada were all endgame.
Duels, fair point. When you could actually get in that is. I managed to get into exactly three of those the first day because everybody was making mistakes during CEs, past that point it was already competing against 20-30+ players in every CE for it. On top of it you had to have equipped very specific actions of which many were different depending on the duel, which meant that you couldn't prepare for them all. I declined 80% of the time because it was the wrong CE and the wrong duel I was chosen for and I knew I didn't have the correct lost action enabled for it. Past a point I stopped bothering altogether.
When it came to fates though, how many were they per map? Twenty something? Not very different from overworld fates, you quickly come to run in circles between them, having done most dozens and dozens of times already.
Bunny treasure hunts were the biggest disaster of eureka to me. Some logograms were locked behind gold chests from those, and they were required for gear progression. Not only the rng for gold chests wasn't stellar (I maybe saw 5 of those in my whole pyros experience), but you also had to pray to get even a slight chance to have an actual bunny because those stupid fates only allocated 8 of them for a hundred of people at release. The chokepoint was real and it frustrated so many players back then. Had to spend millions and millions in gil just to get a chance at those logograms that bunny chests were unable to provide, and I didn't have submarine printers back then to afford that.
I have yes, thus my dissatisfaction with it.
I never saw anybody beat a duel live. They're not that hard when you know what to do, but it has never happened when I was going through it. Either way, not a big deal. I was pretty happy after eureka to see that the leveling progress wasn't too hard. I went through it because I wanted to experience the story. And I'm glad I did because there was a lot of it and lore behind it all, and the endgame instances were actually some of the best creative midcore content we've had (especially CLL and Dalriada). Why do I have to trudge through all that leveling tedium to get to the meat of the content? Make the leveling interesting, I say.
What does "broader audience" even means? More popular? Reaching out as many people as possible with the risk of diluting gameplay quality? But what is there even to dilute in the first place there?
