I recently built a system under very changing directions. I put all my calls into a single controller, so there were some tens of methods in the single controller. It felt nasty, it felt ugly, but when time came to actually keep up the desired functionality, put a break and comb the system, it was great to have a single place from where to extract common functionality from. At this point, it was obvious what functionality needed extraction.
