Mastery expensive ?

the cost for mastery level upgrade is WAAAAYYY TOO MUCH like... for a level 6 mastery 3250 BE ???zzzzz i mean should it even cost BE to upgrade mastery tokens now ? i mean its just cosmetic on the loading screen .. i mean its like the Rank borders we work hard for it we get it for free .. so why not a loading screen mastery level for free ? i mean getting 3 S or higher for M7 or getting 2 S- or higher is hard enough for some of us ... so it costs waaayyy too
