I am playing the game for 184 days. This is the most unfair quest line I have seen so far.
First of all why should I do only 1 quest each day? Second, why the only worthy reward in the presents each day is the daily reward? Third, Why when you get the x2 reward and then open "Show two" it doesn't show 4 boxes? It is a x2 reward after all, isn't it?
Fourth, Why in 3 of 4 cases I should open all the boxes to find a reward worth more than 20k gold (which is like nothing)?
The story line buildings worth nothing if you don't have them all. With the way you made the whole concept I have to open 10 boxes to find a single building if I am lucky. If I am not lucky I save 3 days then open 90% of the boxes and get 3 blueprints and 20k gold. So the chance to get all the buildings is less than 10%..........................
In the picture above you can see how you can win nothing for 70-80 Stars
