A very reasonable explanation, one worthy of being delivered by let’s say a community manager or a game project lead. It’s the absence of communication that is always the issue in releases like this. You (the devs/CM) have completely reengineered the game experience for every current player that has updated, but you don’t provide any context to help the player process all the changes especially given the magnitude of the change. We all know the relics should be appearing but the lack of a communicated explanation is inexplicable.
On the other hand, if the drop rate really is this abysmal, then they need to rethink their careers as game designers. It takes absolutely no time whatsoever to do the math on their implementation to see it’s entirely unsustainable as a path to entice people to play. They make mention of some unnamed primary method of acquiring relics in the future but the poi t of early access is to interface with content and provide feedback. No one is going to be here in a month if the drop rate of relics is 1 every 48 hours for the entire playing community.
