The problem isn't the locked area content. They'll still drop the same loot. Destiny as it is would be awesome if they changed a few simple thing about how the loot system worked. the problem is so many things offer the exact same rewards it makes all the content the exact same once you've played it once. without a decent loot system it doesn't matter for shit how much content there is. great 4-5 new missions, that's an hour tops. 2 strikes? another hour. 1 raid? wont ever get in to them anyway as I dont have friends, so utterly pointless to me. So once I've done that 2 hours worth of new content I'm have 5 new areas to do bounties in and 2 places to get a pathetic level of marks and loot from. the same loot I can get everywhere else in the rest of the game. see the actual problem? specific loot should drop in specific places. like Mars for primary legendary weapon engrams. Venus for secondary legendary weapon engrams, Moon for Chest and Helmets and Earth for heavy weapon, gauntlets and feet. At least then you'd have a reason to do specific things. replaying story missions should give loot as well so you actually have a reason to replay missions outside of bounties.
