Hmm....
It's a multifaceted question. Kellhus and Moenghus the Elder's worldborn half-Dunyain children would get the best chance of their abilities unconsciously allowing them to walk the desire path socially among the worldborn. However, the issue is that desire paths, unconsciously, aren't as short as consciously finding the shortest path. Dunyain lack the time spent in the social milieu, as interaction in Ishual is likely a poor representation of general worldborn human interaction.
And then, of course, when a Dunyain is ignorant of certain facts, moving socially (moving along desire paths) can be made difficult by that ignorance (when Kellhus learns Scylvendi from the women of the Tribe, for instance).
