That is a waste of time I have always done nightfall and weekly on every character then raid. That is 60marks right there so I now have to play on character then to the other which is again dumb and most then likely I will keep jumping from character to character and forget hit the cap. Due to i'll do the daily for vanguard and crucible which will be another 30 or 40 marks (might be less). But after two hours I have near max marks which I will have to go back to the tower just to waste them. It will be so easy to max out your marks and forget you maxed it. Then you do bounties or pvp and loss all those marks you could have earn. Then when there is something you want you won't be able to hold enough marks to buy multiplies of the item.
