Suggest to add 100 opal herosouls for 1 blue dewdrop, with 4 swap chances 
for the Blue dewdrop Some of higher lvl players would be happy. Could vary the ammount, but over all 100 opal souls for 1 blue dewdrop is fair considering higher lvl player has no chance to get the opal heroes , he may have fired, on early days of game 
. And wouldnt be hard to add them up for exchange
