With the new patch coming in today. I would like to point out this gay system that they are implementing so some of our hardcore hackers and Dwar would consider cracking it.
There is now a Fatigue Bar that limits the amount of dungeons you can do. You are given a daily allowance of 700 and it is used up based on the difficulty of the dungeon that you do much like the ABP bar. The amount use will be displayed when you select the dungeon and difficulty. This shit makes grinding and farming impossible. Even if you have a party of 4, it will probably run out after an hour.
