I've been refraining from joining in this discussion, but now I feel the need to.
I even point out that it's from my limited perspective, and that, from a development standpoint, my ideas and observations may have no basis (at least, I hope that's what I'm getting across). If the staff reacted as defensive and vitriolic as you are right now, we'd have no influence on the game whatsoever. And that's exactly why these forums exist, to promote discussion and try to influence the development of the game for the better.
Do not suggest anything that comes from a limited viewpoint that has no basis, please. Randomly dropping in and suggesting changes for a game whose schedule's details you don't know much about is not a good idea, and making long posts suggesting major changes to a release schedule that two overworked developers are comfortable with, which you also know little about, is quite disrespectful degrading. These are developers who strive to make the best releases that are humanly possible and are paragons of diligence, and they deserve to be supported in what they do and offered constructive criticism by people who indulge in their content, and not have their morale decreased by someone who doesn't. Very respectfully, I'm requesting you to rethink your ways and try out the content that is being produced before giving your opinion on it, as that will be constructive to the community as well as the developers.
Fourthly, as I'd said already (making me think you skimmed my comment just so you could argue with me, a poor habit you should give up), I know the Verylus and Sans Robin quests are filler (though, it should be noted, the last Verylus was original art, defeating the point you made). In fact, my point was that those quests, which build on existing characters and develop world lore, are great filler. The Inn challenges, though, are an extra week of nothing for new players while end-game players can grind for a new toy. If they could make their filler content from only reused assets and just put some interesting writing to it, I think that would go much farther for the fanbase. After all, that's the formula used for about 30% of Book 1.
The last Verlyrus quest was a simple reskin of the Trithril quest from the Tomix Saga, with the addition of a few gemstones and white cave walls. On the topic of worldbuilding filler, the Inn challenges do that as well! The Exaltia Tower is a reservoir of Exalted Lore about the Alliance between Celestials and Infernals, which is touched upon in the Last Stand of Ehr'Ishin (a book in the Inn at the Edge of Time), if you know where to look for it. Due to the presence of lesser Augahims and a warbeast, Cryohem, in the story, it is evident that Exalted Lore is soon to become relevant to the main story. The Exaltia Tower's unique animations and assets can also be recycled for main story, which frees up developer time to write more for the main story releases. The Corrupted Seven helps in worldbuilding, too! Tomix' journey seems so much cooler now that we've met and fought all of the spirits that he did and it's something I really enjoyed but rarely touched upon!
Oh also, just saying, Book 1 wasn't exactly the best and the quality of the game has increased roughly a thousandfold since then, and a lot of people really enjoy the new Book 3 formula as well, and imo, if the devs are comfortable with this, we should stick with it. After all, they try their best to give us what we want and we should return the favor.
Never assume yourself to be the smartest and most experienced while the other's an idiot, you're sure to make a fool of yourself.
Callum isn't the fool here lol he's actually bringing up several good points, though admittedly in a harsh tone.
