getting tokens pre ML5 plz

i don't understand why you have to be mastery level five to earn tokens. i got 2 S+'s and like 5 other S ranks on my path to mastery 4 morgana. maybe give us champ mastery boosts for getting s's. it takes soooooo long to get from 4 to 5 anyways. anyone else feel like this or am i alone on this one.
