I don't know about others, but I'm swamped with tasks even at 200% during the first week. The action starts right on the first day, with one battle after another.
(I'm talking about the timer again – let the debate begin :D)
I also saw that some players were doing training runs. What are your impressions?
I would add a time limit to the battles; there are many of them, after all, and it's Diamond difficulty.
