The lore is easy to get by just doing daily roulettes and Vanu beast tribe quests:

Expert - 60 for the roulette + 80 for the dungeon itself
Lv 60 - 100 for the roulette + (30, 40, 50, 60, 100, or 150 depending on the dungeon you get)
Lv 50 - 120 for the roulette
Leveling - 100 for the roulette
Trial - 60 for the roulette + (0, 8, 10, 12, or 15 depending on the trial you get)
Frontline - 50 for the roulette + 50 for the frontline itself
Vanu daily - 3 quests @ 15 each = 45

In all, that's 695 - 830 lore per day.
