You not completing this fight stops you from getting higher ilvl gear. It does nothing to stop the rest of the community from upgrading their gear. I said that the content would be "nerfed" by more people having high level gear. This is true. If your DF group was half new people and you cleared it the first weekend, no one had better then i290 gear(and some people didnt even have that, as they didnt know the importance of doing the lvl 70 class quest first). If your DF group is half new people now, then the other half is likely to be between i300 and i310. In another couple weeks, the experienced half could passing i320. Eventually the other half of the group will be above whatever maximum sync they set for the fight, and they will just have the highest stats possible. Besides that, as time goes by new people will be less likely to be matched with other new people as people will continue to clear the content.
