The adventures are actually very good, including interesting dialogue, character banter, locations, and gameplay. There's just no reward for doing them that progresses your character. They're good, but implemented poorly. They should give you something that advances your character, but that's what happens when you have to reboot every game you make a year away from launch.
Destiny PvP is fucking abominable.
Yea its abominable to you; but once again there are plenty of people that do enjoy it for what it is. At the end of the day, its content, and its a piece of content that A LOT of players enjoy.
