There needs to be more Daily Missions
Right now you get 2 missions a day, refreshed at 11 AM PST, these many missions i believe, is not enough. The first mission (each day) is always "Win a game using the Riven/Yasuo Icon" and upon completing that, you unlock a order/chaos mission that is unique day-to-day. I have issue with the fact that 1 out of your 2 daily missions is simply "win a game" but thats most likely the case because of the event, and ritu having to differentiate between people on the either side of the order / chaos thing, but if anything, i think this would demand more than 2 missions even further! Basically, my assertion is that for missions to live up to their great potential in League, there needs to be more daily missions.
