I understand all that. Earthquake was still down for its refresh when I visited, and I still thought it was an excellent attraction.
But whatever we think of Supercharged (I think it's complete junk!), it was a significant piece of the attraction as one of its headlining scenes, so Universal should attempt to find some way to offset that loss of value* to the rider. Or keep it active until they're ready to swiftly replace it (which is how I also feel about it in Orlando, even as I desperately want it gone from USF).
At minimum, in the meantime, they should try to rework the order of the scenes on the Tour so that it ends with one of the more premiere, "E-ticket" scenes. I don't know how logistically feasible that is, though.
*Not of Superchaged, specifically, but of what it was meant to function as in the larger Studio Tour.
