I'm at the point in the game where one of the quests is to collect two items in the Armory. For the Armory I need 20 Dragon scales and since 8 days all of my 4 daily eggs didn't give me a single one.
I understand that the game sometimes require you to wait but combining it with luck is really unnecessary. Maybe change it for future players that eggs have a higher chance to drop scales instead of the unnecessary souls and coins.
