With how the devs designed the system, you have to grind the same content over and over again, it get's old really quick, especially with only two end-game dungeons. It turns those dungeons into chores that you just want to get over with quickly.
That is partially tied to problems with Alex Gordias (both Normal and Savage), Frontlines(Seize) and Diadem. They were intended to be pretty good (alternate/augmented) sources of Eso tomes, but design errors caused players to get sick of them really quick.

AlexNM's original token reward system caused players to burn out incredibly fast. Even after the reward system was changed players were sick of it and didn't want to go back. An average of 5 runs (which should have given a player a token) of each floor would have given 200 Eso.

AlexSavage's similarity to AlexNM (which many players were already sick of) along with the problematic difficulty caused serious problems. Hardcore players would have been getting about 20% to 25% of their Eso each week from Savage once they started clearing.

Frontlines(Seize) suffers heavily from extremely long queues caused by GC imbalances. It is a really good and interesting source of Eso when you are in one of the low pop GCs getting 10 min queue times, but sucks when you are in the high pop GC with a 2 hour queue time.

Diadem suffers greatly from disparate player goals, anti-poopsocking measures, and imbalanced rewards. 20 ESO for a 90 min duty is not very rewarding compared to 75 for a 15/20 minute one. Once many people got their mounts they just stopped doing Daidem.

There is a lot of variety, the problem is that doing daily expert roulette 5 times each week is just so much easier, faster and less draining than other sources.
