Since the well appeared on the PTS everyone I know has been impatiently waiting for it because it would be one the most significant quality of life features the game ever added:
1. No more waiting and ulti loading while doing damage tests
2. No more fighting over mobs during prime time while resetting the raid
It was a huge disappointment when it didn't release with FoA and I expected it to be a absolute no-brainer to be included in the new crates ( Ayleid Well in Ayleid Crates seemed like a safe call). Now for whatever reason it wasn't and I absolutely can't imagine why. Since there are no content updates to be expected until the next chapter release I don't expect it to just randomly pop up in the crown store. Which is incerdibly frustrating knowing that such a large QoL is available but not implemented.
