There have been many games before that have had raids involving many players, and while yes, coordinating that many is undeniably a challenge, demonstrably some people find overcoming that challenge part of the fun. And in this community, not just others; I know many people very excited about the Savage version of Delubrum Reginae. And although it has a savage designation, that doesn't mean it's necessarily meant to be for the exact same audience as the 8-person Savage content.

Because the Baldesion Arsenal and Delubrum Reginae (Savage) don't need to appeal to every single player, any more than any other pieces of content does. And as noted, I've seen enough people excited about it to think there's definitely at least some interest in it. Whether that proves to be enough interest to merit more of that type of content is anyone's guess.

Even if there is, it certainly shouldn't be the focus of the game, no; normal savage stuff should probably remain the progression raiding content. But as optional content, especially even more optional than existing progression savage (because it isn't a path to the best gear), why wouldn't there be space for one more type of content to tackle?
