A5:
We are truly sorry about the initial issues with the feel of the job. That said, card effects were changed to their current iteration because we received feedback from all regions that players did not want "useless cards." It does indeed lower the feeling of "drawing a good card," but if we make certain cards significantly more powerful than others, then we'll just return to fishing for the good ones, so we decided to simplify it. We plan on continuing with this style for now.
Maybe add a difficulty star system instead (1=easy 3=difficult) so new players know what they're getting into.
Old cards were not difficult and had nothing to do with difficulty. It was just fishing for the good cards and praying to RNG. There was never any real choice involved, just an illusion of one.
