I don't know why people are so fixated on puzzles being one of the magical bullets that is going to make the palace better. Considering that every floor is randomly generated, most of the puzzles would have to be watered down to make it usable everywhere. Regardless of how hard or easy the puzzles would be, it'd boil down to just looking for a guide to solve them faster and waste less time cause no one wants to run out the 60 minute time limit.

If the current floors seem easy now, it's not just for new players; the devs wanted everyone, regardless of character level or gear, to be able to play together and people had been wanting content of that nature for a while. They had to take into account not just current or new players, but players who are on the free trial and players who don't own Heavensward. Considering that POTD came out in a minor content patch, I didn't expect it to be anything major like Alexander. It's filler, but at least I have another option to go for tomestones instead of just grinding Aquapolis and Expert roulettes everyday.
