Crystal Tower has to go

[Gemina]

They haven't done the same with Mhach at all. CT didn't become required as soon as it was tangentially relevant to MSQ, but when they wanted to build on specific events and characters involved in it.

I know. I should have double checked before making the statement. The latter part of your statement though is why I say that they could make Mhach a requirement in the future, and because it still is a requisite for progression, albeit a side story questline, it has me lean that way.

The current void storyline is only relevant as far as involving voidsent, really.

That's pretty relevant. Like really relevant. They are the only life forms we are currently aware of on the 13th, with the exception of Azdaja and Zero. We are also made to assume that Golbez is a voidsent as well. The dev team even went as far as to not create a plot hole with the voidsent we encounter in the WoD dying after learning they can't die during our venture to the 13th this patch. Interestingly enough, they changed the death animation of the enemies in the WoD to match those in Troia.

I'm not saying that they should definitely make alliance raids a requirement for MSQ progression, and I just saying it is one they could tackle the ilv cheese as not meeting level requirements will also reduce the number of instances available in the roulette.
