Title above. I think we should be able to refresh the selection of CoC for free at least once since it is completely random. 50 theonite is too much for refreshing for another random selection. I remember trying to refresh the shop 6 times just to buy a diamond key. Never got it, and wasted 300 theonite for nothing. Very much an unenjoyable experience.
OR, another method that could be implemented could be that we have 24 free refreshes, but once all 24 are used the shop doesn't refresh until the next day. Since CoC refreshes every hour, this means it would change 24 times in a day. I think this would be a fair implement, since it means we wouldn't have to lose potential good mats while we're sleeping. Of course with this method you could probably get rid of the hourly refresh and make it so refreshes don't carry over to the next day to balance it. Just a crazy idea I just had.
TLDR; have some method to control CoC selection/randomness
