I doubt it, the first crota raid I did this week had only 3 titans (they all had second third characters that was also titan) and we finished it in 30 minutes with only 1 wipe at crota, who we killed later without cheese. I don't know a single player in my friends list that does not have a titan, and about 70% of them main their titan. Ironically I believe now the least chosen class is the hunter. I think that is due to the fact that players play the crucible less. My favorite class in the crucible is the hunter btw.
