The wasted potential of the new missions and my thoughts about the mastery system

Missions So i just had about the new missions and i think that riot had a very good idea to put them into the game, but i think they should expand on this system. Like they should add new missions every day besides the first win of the day. Like one day make a mision so get 20 assists and make the reward Blue Essence because its really hard to save up to get new champs (well atleast for me) and especially for the people taht dont have enought time to play this game for 3 hours a day. Anyway this is what i think they could do to the missions. Mastery system The mastery has some flaws i think you shouldnt have to pay BE to upgrade your champion mastery, because that just wastes your BE especially if your trying to buy a new champ. What i think they should do is to make the mission system interact with the mastery system like when you reach level 5 mastery you should be given special missions like if you have a supp which is level 5 for lvl 6 you get 3 missions like place x wards, destroy x wards, shield/heal x amount. And if your a tank you get missions like tank x damage and cc x times. Something acording to your champion and as you level up you should get harder and harder missions. One other thing i would suggest is to add more levels. And to avoid it being a grind just make it fun, think of more interesting missions.

That is all i wanted to say. I dont know if im the first person to write about it but i just wrote because i thougt it would be cool. I would really apreciate comments and other suggestions and what you think. Who know maybe riot will see this.
