Within her opening story "Asylum of the Daleks", Clara was more than a mere human, and had incorporated knowledge which, after she was assimilated by the Daleks, led to the Asylum Planet being defenseless and destroyed by the Daleks. Plus, the knowledge allowed Clara to rewrite any reference to The Daleks within their culture.
It is conceivable that, after the premier episode, Clara after being absorbed by the Great Intelligence, returned with additional knowledge which provided her with additional expertise.... used within "Asylum of the Daleks".
Of course, the post 2005 series is entirely non canon to the 1963-89 series, and one may assume that Sylvester McCoy will return as The Doctor in a future edition of Dr Who.
