A theory about how to get S level ranking easier
The current system determine your rank by how well you perform compare to other players playing the same champion in the same role. This means playing champions that are not commonly played/in the role that they aren't commonly played in will give you a higher chance of getting a higher rank.
For example,
is mostly played in the top lane, but if you are very good at
, you can play him in the jg
and still do very good(especially with
buff last patch). Since
top generally do very good and
jg usually do worse, it will be easier for you to win a S rank.
I have got S on
in the jg
and
mid.
(don't play champion in a role they doesn't work in tho.)
