ARAM-Mastery needs reconfigured after the new bench implementation

As the subject states, I think the ARAM mastery needs relooked into. Just noticed how ludicrous of a score you need to earn an S in ARAM.

Got me thinking. Champion mastery in ARAM was implemented at a time of no bench and only the two rerolls. As such the teams you had, and the teams you were facing had much more limited composure.

Thus scores were much more inflated. Now that the teams are concistently better do to the implementation of the bench, Riot may need to rebalance these again.
