Yes I play this game every day you can tell by my grimoire score. Not being able to bulk buy is going to piss me off greatly and having to check on how many marks I have before I do a nightfall, weekly, daily or pvp is going to suck. Because if you forgot to check you will miss out on marks and the way it currently stands it will be very hard to get marks quickly if you do the major event i.e nightfall, weekly and dailies.
