All the PVE content is essentially available to everyone. It is feasible to get near 100% of the community through it through solid effort. It is only feasible for a small portion of the community to achieve flawless no matter how many tryhards are in it. It's not in Bungie's best interest (it's in there interest to maintain some percentile of happy gamers) to exclude all but the top 10% of players due to one event from the latest DLC from this recognition. Don't mistake Destiny for a PVP game. It is a PVE game with some PVP included but PVP is only a small portion of the content.
