Google's John Mueller said on Twitter that if your content on your site is being outranked by robotted out pages, then you got work to do.
In short, if you have a page on your site that you used the robots.txt file to tell Google not to crawl and it still outranks other relevant content on your site for a query in Google - that is an issue.
John said "If a robotted page from your site ranks instead of a page with content on it, for queries that users use to find your site, then I think you have work to do :-)."

This might be obvious, but sometimes the obvious is not so clear when it comes to SEO and Google ranking.
