You can also earn some amount of endgame tomes from leveling roulette (and most other roulettes) if you do it at Lv80 - a much more varied way of reaching your weekly tome cap instead of just running the three expert dungeons. You can do raids, trials, leveling and alliances to work your way towards that quota - or you can just let it slip for this week. It's only a treadmill after all: do content to get gear to do content....
Ultimately though, it's an RPG, made by a company whose primary focus is single-player RPGs, and with a lot of that mindset behind it. In a single-player RPG you often don't even redo dungeons, unless you need to go back for a later objective or grinding - you just work your way through it once, and move on to the next part of the story.
