Ah, but you're the away team, being deep in my lands and dominion...
The immortal Dracolich Jurri, who singehandedly crushed Vanheim, who ate Pasha the Dawg and who ****s in the skull of courtesy shall eat the Mother Oak of Pangaea, too, alongside every little forest critter basking under it! Molochs don't taste good, however (as evidenced by the infamous HOI-fanboi), so he'll be lobbed to the bottom of the Well of Misery.
I don't think Azhur got the in-game message, btw, being AI and all
I'm not sure if I agree with your laissez-faire view, though; consider: playing the game is a joint effort, many people besides oneself devote their time on making it a pleasant experience for all (in the sense that a well-played game is pleasant). One player quitting disturbs the whole game, making it rather inconvenient for the others, especially if the quitter is significant. Certainly it's common courtesy to at the very least inform the other players of such radical changes like going AI, and preferably the reasons for it!
