The Hextech crafting page needs more information on it
Gems can appear as a result from crafting? What kind of crafting does that mean? What are the odds of it happening? No one has reported seeing a gem from anything but a chest drop so it seems like that feature was removed after the crafting page was finalized.
What are the key drop rates? We have had to sift through red posts to find out that fragment drop rates decrease as more keys drop and this resets each month, but that only brings up the following questions How much does the droprate reduce? How many games will I need to play in a month on average to be able to open my 4 chests? What qualifies as a month? Does that literally mean the first of the month or 30-31 day periods since my first key drop? We also had to wait for a red post to leak that there might be some kind of key fragment drop limit. Can the key drop rate actually fall to 0% if you get too many drops in a month? Is it even possible to get enough key fragments to open all our chests? The rioter seemed to imply that you could only barely get enough keys for all four of your chests. Does that mean that missing the key drop cap for a month means you'll be stuck with a chest that you'll never be able to open without spending RP?
