Vaults and the new Merchants Alliance quests:
-
Require no resources (or virtually no resources) to complete.
-
Can be done quickly (in the case of vaults, in under 30 minutes; in the case of the Merchant lost mariner voyages, in less than 20 minutes).
-
Raise emissary status very quickly.
-
Do not have any impact/passive area denial on the wider map for other players.
-
Result in big payoffs.
Additionally, the MA lost mariner voyages:
- Can be completed (100 percent) solo in a reasonable timeframe.
By contrast, ghost fleets (and OOS quests in general):
-
Are long.
-
Have low payouts.
-
Cannot effectively be completed solo (yes, you can definitely whittle down the ghost ships one by one - is this a fast or practical money-earner? No).
-
Do not raise emissary quickly.
-
Require (in the case of ghost fleets) you to go around collecting a not-insubstantial amount of resources if you hope to complete them.
-
Deny large portions of the map to other players.
Simply put: the ghost fleets (and OOS quests as a whole) feel tired; the payouts suck, the effort/time investment is stupid, and they're activities that really can't be completed efficiently without other players. The experience, as a whole, is dated and tedious. OOS should be high on Rare's priority list to revisit.
