Please no more Eureka!

[Reynhart]

It wasn't, it was supposed to be niche content for a select few, but the mistake was putting the relic in there which has always been a high powered weapon for casual players.

Except that the Tome weapon was a casual alternative for the Savage weapon since the very beginning of Heavensward on top of being a better and more accessible weapon than the relic until almost the very end. Especially considering the most famous Anima step required to go collect items into Diadem, and having 8 different crafter specialists for very high level crafts...completely casual, right ? The only way for them to make the relic weapon shift more obvious would have been to call the tomestones "Tomestones of casuality".

Wondrous Tails was also created to have another incentive to go back to old content instead of using the relic for it because people were bored of the relic just reusing existing content.

So ppl see it and think its content intended for casual players, which they are obviously going to do since relic = casual is kindda part of the game at this point, so ppl cant be faulted for it.

Except that Yoshida clearly stated Eureka wouldn't be. So people felt betrayed by their assumption despite having been told the exact opposite.
Of course they can be faulted for it.
