#A key fragment is more accurate.
I spam S grade games on the week end modes but never on the summoners rift draft.
What I need is keys to drop as frequently as I get my S games but it seems like my ratio is like 4 chests to 1 key fragment.
I don't spend RP on this game I know they want you to spend RP on keys and stuff but the ratio of fragments dropping is so low.
I get the chests as soon as available... which means I only get 1 chest a week :(
its more like getting a key.
