I don't think any of that is Joe Rohde's fault, though. Animal Kingdom, e.g., would be a much worse park if it had 10 mediocre to bad attractions and average theming replacing the top tier headliners/theming that currently exists there. It's not helpful to have more attractions when no one wants to ride most of them -- that's the current EPCOT problem.
It's also not like he was the one spending $500 million on Cosmic Rewind.
Of course there's a middle ground, but that doesn't seem to exist for Disney. I have more faith we'd get some truly great attractions worth of the money being spent with Joe Rohde in charge than with anyone else out there except for Tony Baxter.
That said, Rohde turns 68 this year. He's not that much younger than Tony Baxter. Neither of them would be a long-term answer.
