Evening, Rito.
There's a bug (I think) where the keys for the Crafting System aren't dropping in any of the games. I've won about nine of ten games without receiving a key fragment. Is this a bug? Or is it just extremely rare that these fragments actually drop?
I literally have three boxes that can't be opened because I'm not getting any keys! So frustrating! :( 
HELP
Doctor Jarvis1 votesIts seriously super hard to get them. Even in parties.
Temphera1 votesThat can't be the case because I won three consecutive games and received a key for each of the games when the system came out, now they never drop. Like EVER. Which is odd, but if this is the case then this whole system is completely useless!
Deep Terror Nami3 votesIt's because the drop rate is not linear. You will get a lot at the start, but then it becomes really hard to get more. This resets each month. They've basically made it incredibly inefficient approaching impossible to farm them. I can't really know their actual intentions, but it may be to encourage you to buy keys.
Temphera1 votesThe majority of the purpose that was intended in creating this system was to earn FREE skins/champion/wards. We should not have to purchase anything.
Inefficient is an understatement.
Drunk Tsundere1 votesI haven't gotten a key in 10 or so wins either
TheLastShadow451 votesit's rng buddy. I got three wins and three keys today(RNGESUS was on my side today).
Temphera1 votesPerhaps it may be an Oceania problem then...
lightdragoon881 votesJust to be on the safe side: You are playing normal summoner rift and not ARAM right? I have seen so many topics of this before and a good bit was them playing ARAM which doesn't drop keys yet.
Deep Terror Nami1 votesKeys now drop in ARAM (and TT) since the patch! (I've even received one to verify) http://na.leagueoflegends.com/en/news/game-updates/patch/patch-67-notes#patch-hextech-crafting-and-loot-update
lightdragoon881 votesWell yeah they do now but these games he mentioned could of been a few days ago before the patch. I wanted to make sure.
Temphera1 votesThey do drop keys now on ARAM now, and no I play Ranked.
lightdragoon881 votesWell then as other said, they get rarer the more you get until they reset at the start of the next month.
TheLastShadow451 votesthe three i got today was from aram only.
