Please remove missions that require wins from Event missions and daily missions.
Your shitty matchmaking system fails time and time again to create balanced matches, meaning that sometimes it is literally impossible to get a win, thus missing out on LIMITED time event rewards. There is physically not enough time in the day to get the wins required for missions because of the matchmaking system. Fix it.
