I haven't played nearly as much since completing RoV, but the campaigns that entice me to log in are typically the Unity coffer and Abjuration dials. Double CP should be active much more often, as others have said.
Would personally like to see a campaign that yields more Alexandrites or Nyzul Tokens somehow. Heavy Metal plates aren't that bad when we get the Voidwatch campaigns, and Dynamis currency doesn't take that long to farm these days - but Salvage gets pretty boring after a while.
