This is such well thought out feedback, we really appreciate it! I totally get your thoughts on memories not offering enough unique builds yet - that's something I definitely want to lean into as we add more memories. Defined builds that are best suited to tackle a specific set of omens is something very inherent to the vision of the game, so we'll work toward making that more apparent in future versions.
I also particularly like the idea of offering a small amount of sand as a reward for skipping events.
