Since wiki was a bit confusing about which packs are needed for each saga I've made a short summary:
- Gianthold has 2 complete sagas (good)
- MotU has 2 complete sagas, and also is part of 3 other sagas (good)
- Shadowfell has no complete sagas at all despite it's one of the most expensive packs (not good)
- Even if you had 2 newish packs (Druid's Deep + High Road) you won't have a complete saga (not good)
Consider adding more sagas:
- Shadowfell should have at least one complete saga (I mean if you have only that pack you should be able to complete a saga, because it is as expensive as MotU). Anyway, this is a new pack you are so advertising now.
- Druid's Deep + High Road should have a complete saga too (maybe with smaller rewards, like +2 skill tome upgrades)
- There should be a saga, which contains ALL epic quests (excluding raids, but including all epic challenges) and with new packs this saga should include new quests automatically (but the reward for this saga should be worth that)
- Raids should have a saga too. For example:
- Titan + MA + LoB
- Reaver's Fate + Shroud + ToD + HoX
- VoN + ADQ + Abbot + Citw + FoT
