Don't know if you noticed but your game modes have a tendency of throwing balance out the window and while that's cool and all, certain champs that abuse the imbalance have a tendency of being spammed and that turns something that could be interesting like a 6v6 into a 5v5 + Katarina for both teams
Kalarepa1 votesThey should imo. Let's be honest, LoL is HEAVILY balanced around SR. In any other mode there will be few ridiculous champions (Heca in URF, Sona in ARAM). All the next temporary modes should have bans to prevent tryharders from ruining the fun for everyone else.
Cindikle1 votesThese temp modes need a special ban rule. Top 2 win rate champions get a week long ban. If they can make this work it'd solve most featured game mode problems as far as pick/ban goes.
Tilomentry2 votesUnfortunately I don't think this would work. If 
is on both teams every game, then she'll always have a 50% win rate
