I know, I was meaning they should have done one before opening this ride. They'd know of these problems if they did.
The rides been open for 2 months now. A soft opening, even for several weeks wouldn't have sussed out all of the issues.
It's a highly complex ride system with more LSMs than any coaster ever made, switch tracks, drop tracks etc.
Trying to get it up to top capacity wouldn't have come through in a soft opening period as it seems they continue to find/learn new things I'm sure they have to adjust and tinker with over time adding more and more capacity.
Top it all off by opening the ride in one of the busiest and rainiest periods of the year and it's thrown more variables into the mix they need to contend with.
Basically its taking them longer to get the ride settled and up to peak capacity than anyone has wanted (park goers and universal alike). I'm sure it'll get there eventually.
People have short memories though.
Gringotts was plagued with issues almost daily for months after opening.
Flight of Passage still has constant 2-3 hour waits, which if according to insider rumors are true, this is much more to do with the ride rarely operating at full capacity due to over heating issues they still haven't sorted out in its 2+ years of operation.
Go way further back and Test Track at Disney had 4 months of soft openings trying to work out issues and it continued to have issues for a long time even after its official opening.
Any new/cutting edge ride takes a good long while to sort everything out.
This isn't anything new. Things will get fully sorted out. Hopefully sooner rather than later.
