i for the first time got adam from the HP, oddly enough for completion of golden palace. crystal and rune gave me cianna and valla.
that being said, i always think of the rewards in most cases as an insult to the players. like when you happy to get 5 or 10 blue medals and it gives you 1 instead and when contacting customer service they would "confirm" that you got 1 medal but dont do anything about it. worst tho is the reputation rewards on the shuffle and i am certain that no player, no player ever, not even one that started an hour ago would go "OMG YES! 10 REP! I so needed that!!!!", let alone 10k coins or 5k credits, etc ...
