I think "Unstoppable Union: This trait no longer grants an unblockable boon. Instead, it removes movement-impairing conditions in addition to its previous effect of stunbreaking when activating beastmode" is actually the trait you are speaking of, which has had unblockable removed completely.Additionally, Clarion bond and call of the wild's unblockable are now limited not only by time but by total attacks (2 and 3 respectively). I believe this means the first couple of strikes only of rapid fire will be unblockable under any circumstances.
