That just proves that doing any content will put you well on your way to capping Esoterics without spamming 60 dungeons. It`s Saturday and you`re 390/450 while doing other things not related to grinding the same 2 dungeons over and over. Unless you really need to cap right away, you can progress at a steady clip and have the option to bulk farm if life requires you to not log on. My little foray into story time was just meant to show that I never felt obligated to hop into a dungeon just for tomes.

As an aside, 5 Esoterics for levelling roulette is not worth it in my mind. The exp boost on a lower level job is a better use for that. Expert roulette every day + Alexander NM for your weekly should be all you need.
