Hextech crafting key fragments
I know there is a limit of key fragments that you can receive per month. I'm sure that this number is getting tweaked still since the whole crafting system is still new to the game (which I think is a great idea in general, especially for those who like the random factor). However I believe that that key fragments can get a little confusing. I know I run into it all the time. I know that my month resets because i actually start to get the fragments, and the chances of getting these shards starts to slowly decline the more you get. But I think that implementing a counter of sorts would be a great idea to put in the future.
There's a counter showing how many boxes you can get, and how long you have until the next box. So why not put in some sort of similar system showing the total amount of key fragments that you have available that month. Perhaps even break them up same as boxes. since you get 4 free chests per month, maybe implement a system where you get 12 key shards per month. This can be broken down similarly like the boxes with a time frame to each one, or all together but showing how many key fragments you still have available to acquire that month.
Just a thought for the future of the crafting system. I would enjoy something like this, and I'm certain that many others would appreciate this as well
