Understanding a site from a hierarchal view is essential to any analytics implementation however SiteCatalyst falls a little short in what can be offered outside of the use of classifcation heirarchies.
I would like to see s.hier variable ability to pull any calculated metric or sucess event along side the basic metrics available today.
I would also like to see the ability to define evar based heirarchies similar to how we can with classifcations heirarchies today but on standard evars to create further ad-hoc drill down reports. This is something that is offered and works very well in Google Analytics Custom Report feature http://support.google.com/googleanalytics/bin/answer.py?hl=en&answer=98527.
I feel SiteCatalyst should more capable in the above areas.
