Yes, I do know. Please reread the full discussion in which I was replying to. The guy was saying that a Druid or Wizard 20 was far and away the most powerful thing in the game. Even moreso than someone who's multiclassing, which includes things like the Druid/Planar Shepherd or Wizard/Incanatrix. But, alas, in his opinion, that actually makes them weak because nothing compares to the awesome might of a single-class Druid or Wizard.
