Year 1 Destiny:
Players had access to all the same content and drops, regardless of playing 1 hour a week, or playing 40.
Year 2 Destiny:
Players now have to log in daily to check what quests, and then have to get a group to do specific content before a 24 hour time frame elapses.
So you're saying that that makes sense and is fair?
Lets take the example of what Year 2 is to extremes, as an exercise in how dumb it is to Time gate things.
The Black Spindle heroic is only available to be run 1 60 minute window that is randomly determined. If you don't run it, you don't get it, Ever. It never comes back around again. Once that 60 minute window is up, everyone is locked out.
Does that make sense? Probably not, because Its an extreme example; However it is exactly what happens to a large number of Destiny players simply because they can't log in during a given window of time.
Time Gates on content deliberately punish you for NOT playing the game.
Think about that for a minute.
Other examples of things in game that would completely change if they were under Time gates.
Kings Fall can only be run on Tuesday, September 1st. It is completely closed for a random number of days after that.
Iron Banner can only be run Wednesdays, October 6th. It is completely closed for a random number of days after that.
Court of Oryx is only open on November 11th. It is completely closed for a random number of days after that.
If you don't log in on those days, oh well, you should be more dedicated to playing the game to achieve that "other layer"
