Some of vy players feedback :
They feel like the low lvl map drop rate seems to be a bit too high as they tested it
They also added that the final boss of those scenarios should drop only low, high and chaos since insane map should be a distinct lvl of treasure maps. Partially they agree with the idea of the game less grindy/time consuming but emphasize that the game still should hold up the high value items not giving away everything to anybody.
