As someone who has been the victim of the Rise of the Resistance virtual queue nightmare more than once, I'm sympathetic to the folks who tried and failed to get on Ministry. With that said, we are still in "free" previews, no? Getting on the ride should be seen as a bonus, not an expectation, especially since people reading here should be well aware of the ride's problems.
Now, as
@Tbad556 suggested, when it comes time for paid previews that approach the price of a regular ticket? That's when I think you have more of a right to be angry there isn't more of a stable plan, if there isn't one.
