Let's take a step back....RockIt was built as a quick attraction that was going to be connected to CityWalk. They went with the fastest and "cost-efficient" contractor. It was a novel idea at the time, ride the coaster, pick your soundtrack. It had the omni belts like HPFJ to "help" capacity. At the time, HRRR was going to be a plus to CityWalk, not something that was going to draw thousands of guests. Universal eventually decided to include it as part of USF because at the time, USF was struggling and needed to draw attendance. The ride got some theming made up for it last minute and here it stands. HRRR was not intended to have the same max theoretical capacity as something like Hulk or Dragon Challenge or be a full ride like it.
Today, the ride is the way it is because of some engineering issues, but also because of what it became is not what it was designed for. The ride will never have Express because the capacity for an hour just isn't high enough to meet that 15 minute guarantee without severely and adversely affecting the line. I know this because I took my Premier pass to the parks one day over the summer when they just happened to have a field trial of Express at HRRR. Express wait time was nearly 45-60 minutes and the regular line was at around 180ish. Needless to say, Express didn't last long. Same reason the ride's Single Rides line gets to be just as long as the regular wait time sometimes.
RockIt does seem to have its fair share of technical issues, but so do all coasters. This one just happens to have onboard computers that make issues stand out more.
Also, there's no rule that USF can't have weather related closings. Just because it doesn't follow the pattern in doesn't mean it was a waste.
As a coaster, RockIt when smooth is a blast and still one of my favorite UO rides. That being said, I don't think it would kill Universal to update the soundtrack.
Its time that we stop beating the dead horse and demanding the ride be shut down and scrapped. It still attracts a ton of people and I'm pretty sure given the number of survey takers that UO is well aware of the feelings and issues with HRRR.
On a side note, I was recently told by a park employee working there once that the ride's designer killed himself shortly after the ride was built.
