What is the purpose of doing the whole raid in hard mode?
I suspect that many people will only do Crota once a week, rather than the full raid. Though that was pretty much the case with Atheon too.
The only difference is that it was so much harder to get your raid armor to drop in VoG that a lot of people ran the full hard-mode just for a shot at another set piece. But after 6 weeks of the much more generous RNG in normal CE most people have enough gear to get to 32 so there won't be as much interest in doing all of hard CE.
People doing full CE Hard runs will be doing it for materials for alts and chances at Exotic Weapon drops. The only reason to do VoG Hard was for Exotics and Fatebringer really.
