I actually agree, that could be pretty fun. That said this puts a lot of work / pressure on the DM so it is definitely something to be discussed rather than used to be lazy. (To be clear, I am not reading this into what you said. Just saying it out loud is all)
A completely ridiculous lie on their part. What sane person would give /Microsoft/ any benefit of the doubt whatsoever? (nobody here so far, just saying in general) Microsoft owns insane cloud infrastructure and are also the publishers of the game. If there’s a problem, it’s one they chose not to address, not one that was simply “underestimated”.
