I think Ashlee & Sophia have lost their impact.  They are just mean, boring and predictable now.  I think they have outstayed their welcome and have run out of ratings value.

Have you noticed how they only target female teams?  First it was Angela & Melina, now it's Jenna & Joanna.  They aren't game enough to take on the guys I think.

And Sophia's facial contortions seem to have become more pronounced as the show goes on.  Sometimes she looks like she may have had a stroke!
