First of all, I would like to point out there just because it's a water ride, doesn't mean that it's designed to get you wet. Look at Pirates of the Caribbean, it's a water ride, but you don't get seriously wet. Granted, Pompeii is a ride that's supposed to get you wet, but frankly, looking at it now, putting such an awesome show building onto a water ride seems like a waste, as awesome as it is.
Just as it is reasonable to get wet, it was also reasonable to ride it and not get wet with some skillful seating. That's honestly the reason I would ride it, is because I knew where to sit without getting wet so I could actually experience the show building. However, those jets have turned that ride where the wetness was dependent on skill to luck, and there's simply no good way to enjoy that building anymore.
I really wish there was a way for the park to turn that ride into something else, but there's really no way to do it well.
