Unpopular opinion on Mastery 6 & 7

The Mastery 6 and 7 definitely have flaws, like not having any blue essence, but i feel like the overall idea of how Riot did it was actually good. The fact that it takes something that is actually hard to get makes it so unlike with mastery 4 and 5, you use something that is VALUABLE, something that you don't have unlimited of, so if you have a good amount of blue essence (like me) you don't spend it on any and all champions you get two S shards with. You save it so you can use it on your main the second u get the chance.

I just felt like putting this out there to see how people react and i guess to see how down voted i will get.
