Confused about hextech - need some help
so i just played a ranked (note i only played aram this season until now so i have no clue of hextech) and i got an S+ with amumu(and i own amumu) but no chest. arent i supposed to get a chest for every teammate that gets an S- S or S+?
and keys (fragments) were random on wins right?
ps: never was punished so yea i can earn them
