I'm sorry that we are just now seeing this message. Madman has surgery last week and he's been out of it and I started a new job!
To answer your question, I agree that the loot respawn should be adjusted. It was lowered when there were 60 players between the two servers, but it's not as necessary now. We are currently reviewing the new release of A18.3, so we will handle the respawn timer once we know if we have to wipe or not.
Thank you for your suggestion!
