Legitimate viewpoint to have, but remember to think about how the game is formatted. Daily heroic story and vanguard bounties for exp in pve. The game is based around maintaining a level progress that players can keep up with easily on a day to day basis. You start putting in something that can be grinded endlessly for rewards you now put the "casual" player at a massive disadvantage. Before you jump on me for defending casuals, you should know I'm a pretty hardcore player myself. But anyone who's played other mmo type games can see how much effort Bungie put into making sure that a skilled player with only maybe a dozen hours of playtime a week can keep up with even the most hardcore random pouring that many hours into the game a day.
