Riot I feel as though mastery 6 and 7 shouldn't require blue essence

I think that making these masteries require blue essense completely ruins the fun of getting 2 S- and 3 S's because it forces you to buy hextech boxes and keys to get the required blue essense. Riot made a statement saying if you play well then achieving this should be easy but the idea itself shows how much of a money whore riot really is. In my experience even after winning games and getting an S- multiple times I did not recieve a key fragement or a crate. This wasn't the case before masteries 6 and 7 were introduced. This can lead to the conclusion that riot made it harder to get them to force people into spending money to achieve 6 and 7 masteries for pure profit of the summoners that want these cool masteries to display their skill. Even when I look at their statement about masteries 6 and 7 they were suppost to display skill but to me they only display how much money you are willing to spend to get the blue essense required. P.S. if you wish to fix this then getting the tolkens should be enough to get the mastery and even then why have tolkens when you could just get it after
