Make Missions more engaging and diverse.
Right now all we have to do is, win 1 game,win 1 game in summoners rift,earn 15k gold,get 5 kills ( this adds up so you dont need to get 5 kills in one game but you can get 1 kill per game for 5 games) There is no challenge in missions at all,everyone can solve them so easy , especially that they are available in co-op vs ai. Make missions harder to solve,make people who solve missions feel some sort of achievement. Right now they are just solving themselves without you even doing anything but normally playing like they are not there.
