"Your site has been assigned special crawl rate settings. You will not be able to change the crawl rate."

Speed is part of the algo now.
Your crawl rate has been reduced (I'm guessing).

What type of signal do you think G is getting about the speed of your site, what would a reduced crawl rate tell you about G's perception of the speed of your site, and what do you think you probably need to address as a priority? IMO It's not the uniqueness of your content... ;)
