When there is something I want I will go and buy it in bulk. I just spent 170 marks on all three character to go buy rare sparrow to up grade. With this new system I will have to stop and buy one then grind again. Or I might forget to got to the tower and lose out on marks as I at max if there were 200 each character which we are use to then I won't forget how much I have made on one character. I like to stock pile enough marks so I can bulk buy items.
