I think the problem is is that people are forgetting the fact that Bungie didnt give us the entirety of Old Russia or the Moon to explore. Not only were some areas blocked off, like King's Watch, in Old Russia but some areas werent even in the beta or alpha for a chance to explore in the game like the dead ends behind the Hive Shrieker on Earth and the two OP knights on the moon. This game is going to be huge. People need to stop worrying.
