S Grade and Keys.
I have been getting "S" grades on champions and receiving no keys. I am wondering why this is and if it is a bug will i be refunded?

S grade has no effect on if you get keys or not.
This: it is based on winning. Also, every time you get a key fragment, the next one is less likely to occur. This chance loss compounds, but resets on a monthly basis.
Is there a spot on the sight that explains this in detail? If so could you link it.
Apparently i know nothing...
Last paragraph I think! https://support.riotgames.com/hc/en-us/articles/207884233-Hextech-Crafting-Guide
Cheers everyone, thanks!
