A less severe decision would be defining together a criterion to put in the description of the category, for instance: a multi-Doctor story requires the interaction of at least two regular incarnations of the Doctor. In my eyes, deleting the category at all would make our Wiki poorer.

In the pages about the multi-Doctor stories (List of multi-Doctor stories and Multi-Doctor story, that could be merged), we could include and specify any other case (not-regular incarnations such as the Valeyard and the Dream Lord, flashbacks, Doctors not meeting one each other...)
