Since Prime Resurgence, Nightwave rework, Baro Tennocon relay and cyclic event schedules. The only way to truly miss something in this game is to willfully ignore it.
I don’t know if there was another nightwave rework, but he one somewhat shortly after its release definitely did not change anything about the fundamental core issues of the whole thing. Baro isn’t new and prime resurgence sounds like yet another grind layer, but their description is too obtuse to really understand anything.
Prime resurgence is a less predatory version of prime vault. It allows free players easier and more precise access to unvaulted items, including armor and accessories that were previously impossible to get as a free player.
See the price drop for Glaive Prime today. Dropped off a cliff because its unvaulted.
