When you create a website with responsive design steps for 3 or 4 viewport steps, you end up with 3-4 navigations in the html that the Google Bot reads without CSS ("read as Google Bot" in Google Webmaster Tools). If you have 50 links in the navigation you end up with 150 or 200 links total. Unless you cut down the navigation to significantly less links on some viewport steps, this amount of links might influence the flow of juice of the internal navigation a lot.
What is your opinion about this and how do you deal with masses of links that multiple fixed viewport steps create?
