I felt the questing was really good in Rift up to 50. In terms of NPC motivation - the quests were all pretty basic go kill/collect/use but Kain, the Cult Sagas etc made up for it.I mean you could potentially do the Life Saga from level 15 to 50.It fell off a cliff in Storm Legion though.
You noticed? It doesn't get much better at 60.
