When entering lobby you roll a dice, there’s about 50% chance that you will see one of the following messages:

• Are you X from last game?
• Who is filled?
• 15 it
• Let me X role

The next thing that will happen is that all 4 other players start flaming each other. If you roll one of those events, your only chance to win is that the same thing happened to the enemy team. If either team rolls those events and the other team doesn’t, the game is decided. Can Riot do something about this?
