I like that every dungeon that we get now is linked to MSQ. In stormblood, only 3 patches had a dungeon linked to the MSQ, while on shadowbringers we will get 5, one for each patch... It makes the MSQ more engaging in my opinion, since you have dungeons a lot more frequently to spice up the gameplay. I don't see the need to have 3 dungeons on expert roulette instead of 2, all dungeons are linear corridors with 3 bosses, I don't know how having more of them would be useful, the only thing that changes are the visuals, the mechanics are always easy.
