Greg - Serious question - How is that air frame on the Max8 faulty due to engine placement when the A320NEO has almost the same design?

[salawat]

Because the A320neo can fit the engines under instead of in front of the wings, thereby negating the nacelles contribution to leading edge flow separation.

[GregTravis]

Exactly. Except it’s not flow separation that is the problem. It’s the lift that the nacelles generate combined with their mass and moment far ahead of the center of gravity

[salawat]

Yes, my mistake. Stated the outcome, not the action that gets you there.
