If your grinding for marks for a gun from the quartermaster of some armour pieces its always helpful the know whats the most , efficent way, right? Well here are the averages for the time and the marks you will get from crucible game modes.Note> (I'm on Xbox One so I will not be counting any Play Station Only gamemodes) (All game modes produce 3 marks if you win and 2 marks if you lose.) Control, 7 to 13 minutes to complete a match. Clash, 5 to 10 minutes to complete a match. Rumble, 4 to 8 minutes to complete a match. Skirmish, 6 to 10 minutes to complete a match. I personally enjoy Clash the most, but thats just my opinion. I think its the fastest and I'm a team player. Hit me up on Xbox One if you ever want to play. I hope this helped. And my RNGesus be with you!
