Right. Look at all the trouble they had with Jaws and Kong for years. I'm convinced the only reason they keep ET is because of Steven Spielberg. Once he's gone, they'll demolish it immediately.
They deferred refurbishment on Splash for years because they knew it was "problematic" and didn't want to spend the money until a new theme was chosen.
There's no excuse with ROR though. They make bank on that ride with individual LL purchases that could easily fund ongoing maintenance. And the ride itself typically opens later, closes on time or early every single night and is rarely open for events.
