Should Qing Wen's sometimes be a bit harder?

Hey guys, I've got a question.  Do y'all think it's about time for some of the Qing Wens to be more in the intermediate range or higher?  I mean, I learn something from almost every QW lesson, so don't think I'm upset.  I just feel they are always aimed at the elementary level, and I'm not so sure it has to be that way.  Anybody agree?  Disagree?  Any other thoughts?
