We didn't get a deep dungeon this expansion because of Bozja

[ThatGuySaysHi]

I'm of the opinion that Deep Dungeon-style content is one of the largest factors behind the considerably diminished quality of the player base's understanding of, and performance in, the game. It allowed people to level without ever learning a rotation, how to manage CDs, Etc. because 90% of the instance was killing mobs in seconds. At least Bozjan requires players to focus on single bosses for several minutes at a time, and require them to also AoE for chunks of time as well.

Deep dungeon not returning is the best combat content-related decision Square has made with this expansion.

All of this. Bozja is not only less mind numbingly boring, but also promotes actual practice and skill development. Deep Dungeons are a terrible leveling design/choice. I like the idea of making a pre made and trying to make it to the top with it getting progressively harder as you go, but for leveling to max level? Nah fam. Big yikes.
