Chest daily quest

So, now that chest are being (almost) fixed, i still feel that the 60/40 % probability drop nerf is impacting maybe a bit too much in the game economy. Now you need lot more energy and more bronze to reach your upgrade threshold, and I think this is even more relevant at first level (since bronze production is lower)

So i came up with this idea
Having some sort of daily quest that automatically increse the % drop chance
I'll link it to the number of chest opened, so it still push people to open to get some benefit later the day
For example:
Open 300 chest -> % of dropping something goes from 60 to 65%
Open 600 chest -> from 65->70%
Maybe a third and last "objective" could be at 1000 chest daily that lift the % upto 80% (or more, up to you). Wont do it back to 100% since you still got the rune charge and after 100 chest you got for sure 10 chest that are full
% and number of chest could be adapted later on. Don't know if its possibile to have single chest quest (what i mean is having single quest for wood chest, one for bronze chest and one for silver etc) or if its easier to have one that count all
