Technically it isn't a lie but it’s very close to being misleading: The phrase “on a rolling basis” is intentionally vague. It technically means things will happen in succession over time, but not necessarily in a strict order. Bungie never explicitly promised a fixed rotation like “W1: Spire, W2: Ghost, W3: Prophecy So when Spire shows up twice in a row, they can say: "We never said it wouldn’t happen. We just said dungeons would roll" Why it’s very close to being misleading: In most contexts, players interpret “rolling rotation” to mean a consistent and even cycle. Like how Nightfalls, Crucible modes, or seasonal activities rotate weekly. Bungie even said: “one per week on a rolling basis”, which implies a weekly changing cycle. Having Spire show up twice in the first few weeks breaks that expected pattern and creates disappointment
