New Player Experience Sucks! - Impending Expansion Problems

[Alucard135]

It's not clear how this would happen at all. An option MSQ changes nothing for those invested in the story. Your playthrough will be literally identical no matter the state of the MSQ. It seems like you think an optional MSQ requires the removal of lore from the game, but that clearly isn't the case, after all story skip doesn't require SE to remove the story.

I think they mean that you can accidentally do a side quest that previously required MSQ to unlock. Think of something like doing Omega raids before doing HW 3.5 MSQ.
