Treasure Maps in a bad place (Timeworn Br'aaxskin Specifically)

[LibitIncarne]

Semi-related, but my roommates and I were running the lvl 70 moogle maps/Gazelleskins a while back, and we kept getting the stupid roulette portals. I don't remember if it's still supposed to be 50/50 on the roulettes/normal door maps or if they changed the rates but the roulette maps are so much worse in terms of gil and are barely worth the effort. The level 80 maps have the same issue, and we just gave up running those because the enemies are so much spongier thanks to how the stat squish affected ShB content.

The rates are more like 30/70 or even 20/80 on level 70 maps. It desperately needs changing to 50/50.
I am currently at a ratio of 17 canals to 66 altars from portals.
