The ATPL, and more recently MCC, are designed to ensure pilots of multi crew aircraft have a minimum level of competency in the technical and (more importantly) non-technical/CRM aspects of operating a complex, multi-pilot aeroplane.
I may have mis-interpreted your wording but I hope you were not serious when you imply that non-technical/CRM aspects are more important to the safe operation of a multi-crew aircraft than pilot handling skills?
It's no good being a nice bloke with all the right warm and fuzzy CRM buzz words if you lack the basic handling skills to safely land an aircraft in a 25 knot crosswind on a wet runway or fly a raw data manually flown ILS on instruments.
