Considering you have to grind from 65 to 70 in order to level up, it would be nice if some stones dropped at the same time. I mean, grinding for level can be a bit monotonous, so by having the chance of dropping stones aside would actually be bright and pleasant.
Furthermore, like previously stated, it is causing some game limitations since as soon as you hit 70, your goals kinda get messy such as upgrading gear. Certainly this fact has been reported and it will be fixed asap. For now, all we can do is keep playing and enjoy the feeling of being "online" again in the time being.
