Not sure I can really agree with that. Softball is a much more offensively-minded game now than it was even five or ten years ago, much less twenty. The mercy-rule has come under serious fire because teams can now legitimately hope to make up an 8-run deficit (Michigan had multiple 8+ run innings this season), something unthinkable back in the 90s.
The reason that elite pitching continues to be the name of the game in softball moreso than in baseball is the fact that underhand pitching is much less abusive to the human body than overhand pitching is, so that combined with the 7-inning game as opposed to 9 means that it really is possible to ride two pitchers through a season, and often just one through the post-season. You don't need a pitching staff in softball the way you do in baseball, you just need a couple of elite pitchers. Softball already doesn't have a mound, the NCAA has been cracking down on rules regarding pitchers staying on the ground, going straight forward, etc., and offenses get more explosive all the time. I'd say the game is in a great spot right now.
