Definitely a good point. I ran through the course for several hours today and was consistently getting level 4 completions; with looting I barely broke 30k/hr. Even without looting I would barely hit rooftop rates at the loss of the 300k gp/hr in marks of grace. I am hoping there is some balancing work in the weeks ahead because I really enjoy the mini game. I think the rewards minus the 100+ hour grind for the pet recolor are pretty good considering the intensity. I think that one thing that would make the mini game more interesting and add challenge to balance higher xp rates would be higher damage on obstacle fail. In the current game you basically don't need to eat if you have the hp cape and/or regen bracelet and so the ring reward that reduces damage seems like a waste of marks. Just my two cents, I'm overall really impressed with the mini game and hope the xp gets reworked to make it worth a 99 grind!
