I got on today to see that the rewards for the vanguard heroic strikes playlist only gives out experience for rewards instead of also giving 10 legendary marks like it did yesterday. I completed the daily thinking after i did so that it would now give me legendary marks for the heroic playlist but still it only says experience as rewards. Just to see if it would give me legendary marks anyway i did two of them which none gave me legendary marks. Is there something im doing wrong or is this a rare issue thats only happening to me?
