Despite Joe Blackburn's tweet a month ago, Eyes of Tomorrow is still not dropping for day one raiders who have been farming the checkpoint. Either Bungie has given false information to Joe, or has led the community on a witch hunt in order to increase raid engagement numbers. Further clarification is needed on this subject matter. Does it only count for Taniks kills? Full clears? Because at this point, it's unacceptable.
The way I understand it, the drop chance goes up a small chance on the first clear of an account per week. Just because you're having horrible luck (my bud is as well) doesn't mean you were lied to. You're just pulling a Dudley because you got 37 presents this year and got 38 last year so you feel entitled to at least one more. Stay calm and grind on.
