Solution 9 should not be a requirement to access level 100 scrip exchange

[Jojoya]

It was an oversight.
In Stormblood, Shadowbringers, and Endwalker you get access early on in the minor city for the expansion.
They forgot that the unlock quest was in the penultimate zone this time, and fixed it in 7.01.

There are two different issues being questioned here.

The first is access to the Tuliyollal Scrip Exchange prior to S9 in general. That was fixed in 7.01.

The second is access to the level 100 scrip items prior to reaching S9. That remains the same. One of my alts has one DoH and one DoL to 100 but is only on the level 91 MSQ (about to do the first dungeon). The Tuliyollal Scrip Exchange still does not list the level 100 related items for her. She can't purchase materia XI and XII. She can't purchase the DT Folklore tomes. I will still have to continue the MSQ on her to get to S9 before she'll be able to purchase those items.

If that was also oversight, SE could have fixed it at the same time. Instead it appears to be a deliberate decision.

Again, personally I'm glad to see it happen if it's going to keep the worst of the botting out of the initial endgame gear market. The bots will catch up eventually but at least for the first couple of weeks we'll have a player driven market instead of bot driven market.
