Remove all refactoring functions and let ReSharper do them right
Whenever a new VisualStudio comes out I try to use it without Resharper. But it's always/still missing so many things or they aren't as comfortable to use as in Resharper. I recommend you simply remove all duplicate functionality and let Resharper do them right.

I think this is a very bad idea. Resharper is a commercial product. Removing functionality because a commercial third-party add-on can do it is a step in the wrong direction because less people would have the functionality.
