It’s more of a buzz word than anything. It will be evolving in minor ways, but nothing dramatic. The following things are not indicative of an evolving world: 1. Replaying the same missions and killing the same named bosses from several story arcs ago. 2. Public spaces that never change to match the state of the universe save for maybe a singular seasonal activity. 3. Grinding for the same exact weapons that have been reissued but with no differences whatsoever other than their allowed power level. Those three thing alone encompass the majority of the game as we play it, and so the world does not feel like it is evolving. To be fair, the game would need an overhaul of sorts in order to actually pull it off. And so we have big dreams for the game but little delivery.
