Mastery lv 6 and 7
the biggest thing hindering getting these right now, is getting the blue essence, or shards/permanents of the character - not what it should be, which would be getting the S ranks...
it taking months or even longer to get these bc of arbitrary things you get randomly (and you get them far too slowly) seems to be improperly balanced, when obviously your skill as that champion should be the thing hindering you from getting these masteries.
remove the need for blue essence / champ tokens, and leave it to just getting the S- or S ranks
