I think something should be put in place to elevate the value of a 'real' RP, so SP/RP pitchers don't dominate the position. Putting in a weekly starts cap is one method, and probably the easiest. Modifying the scoring for RP's could be another approach, but we've thrown those ideas around and they never got much traction (something like adding HLD+SV as a category).
If our only option is to limit starts, then I would vote in favor, but I would personally prefer to find a way to naturally bring the value back to RP's, allowing teams to pick whatever strategy fits them best (part of the fun of fantasy sports). Either way, I'd push for implementing in 2012.
