[2022] Can you guys confirm from now on that every new class release we will get have a powerpass/event?

No; as maintained, we do not have plans for powerpasses to go out with every class release, and this has not been the case with all class releases so far. It was indeed a surprise to give another Punika powerpass to players, as the Machinist class is highly popular and we received a lot of player feedback around folks wanting passes for this particular class. As a live service game, things are always subject to change due to player feedback.
