There are times personally when I preferred the Ferengi B-plot and wished it'd been the A plot... or the only plot. Such as Meridian.
And I liked Ferengi eps like Magnificent Ferengi and that one where they go to Roswell so much! So funny!
Not as big of a fan of the writing for the Grand Nagus, or of Gaila in general. But I think what Ishka was doing was brave and vital. And, since the Ferengi weren't like they are in the past- I'm not complaining if the shed their greed and oppression of women.
