We're long overdue for this change, kabam....
Stop forcing us to 100% heroic mode before we can play master. The only reason I even touch heroic is so that I can get to master. Many of your player-base are adults with jobs and likely kids, and are very limited on when we can log in and for how long. By the time we've been able to autofight-grind our way through heroic, the monthly event is nearly over. We're not all seatins, who Havre found a way to make this game their job.
Master mode needs to be available from day 1.
