Dungeons, are you excited to run them?

Are you excited to run dungeons in this game?

I’ve logged over 100h so far and every time I have to run a dungeon for something, being Prophecies or simply to slap LP on an legendary, it’s making me want to exit the game and never log back in. The design feels horrible, dead ends, tiny corridors, lots of backtracking, while movement abilities are very limited compared to other ARPGs.
What’s the design logic behind these annoying places called dungeons? Temporal sanctum can take me up to 7-8 minutes to just reach the boss, if I get bad layout and constantly have to swap between the realities. They feel underwhelming on every level I can see them.

Is this just a me thing, or there are others in the same/similar boat as me?
