I only do expert and trial roulettes every day, and the ex primals once each every week, and this caps my tomes with ease, usually by the weekend. It's easy yes, but I have to disagree that it's tedious. Capping myth in 2.0 was tedious. We only had 1 dungeon that dropped them (till they added them to WP) and the HM primals, which only gave a few each. With soldiery we have what, 8 dungeons that give soldiery?

Just use roulette to keep things fresh, or queue for different ones frequently.
