Umbrellas...? And less content...?

[Zakon]

Palace of the Dead to floor 200, Heaven on High to 100, Maps.

We do maps, but I wouldn't exactly call those challenging or engaging, likely even less so than the dungeons. It's random as to if we'll even find them in the first place, progression inside of them is random, and the only bosses in them are on the bottom floors. If Shadowbringer's maps are different, I wouldn't know, as our luck hasn't allowed us to progress past floor 3.

PotD and HoH are old content where our jobs' abilities would be more limited and thus less fun to play. I'm sure eventually Shadowbringers will get a deep dungeon, but it's not there right now.

Additionally deep dungeon requires all four of us to be present and that's not always possible, usually we're running a man down, which the duty finder makes up for.
