One of the complaints I had read about it when researching was that the complainant didn't like how you (apparently because I haven't looked in depth yet) had to pile on modifiers to increase a target number when they just wanted some situation to be difficult (I think in their specific case it was the troupe trying to deal with a belligerent npc).  It was on Reddit so I wasn't going to ask why they didn't just...set the number o_O does something fundamentally break if you do?

I do actually have one of the things from their website to try out, I just haven't got around to it yet aaaahhhhhh ^_^;
