Duty support with NPCs really adds to story immersion which is why I run new dungeons with NPCs at first. It also gives me time to explore the dungeon and enjoy the scenerie. This is usually not possible with other players because everyone is just rushing from boss room to boss room. I can also learn boss mechanics at my own pace without the negativity of other players. The system also helps me whenever wait times are too long, so that is another plus in my opinion.

Therefore, I really appreciate the duty support system and I would like to see it expanding to trials as well. The Mothercrystal duty was already a good start. I loved the interactions between the NPCs!
