The Prosperous and Training trait drops are as high as 60-70% in some Undaunted runs treasure chests etc, The same is true of handing keys in. They are not included in the 12 person trials so why are they so highly present in other aspects of the game?
It is fair enough that they are preesent on the starter Islands but can be of the same proportion in the rest of the game, Given how fast players are now able to get to CP160 what is the function of having such a high and statistically disproportionate drop rate of items with these traits?
