I've mentioned this before, but the distribution of silver is poo.
common chest = 25 silver (1 hour) >> change it back to 50
rare chest = 50 silver (2 hours) >> 75
big rare chest = 75 (4 hours)... << This has to be 100 silver, if not more.
epic chest = ? (12 hours) << Should be 12 x common, again, if not more.
legendary chest = ? (24 hours) << Do me a favour!!
mythic chest = ? (36 hours) << Wow!!
All this says is that it's more beneficial to win common chests.
Well, that's stupid...C'mon devs, sort this out!!
