Stop kicking people from your group that are playing free to play champs
When Ahri was free during the free week I was trying to play her in team builder but everytime I would get into a group someone would say kick ahri shes free this week and before I can say anything I'm kicked. I own Ahri and play a lot of her but even then it's norms and norms is where you try champs and sorry bots is not good practice. If you want to play where there are no free to play champs then go play ranked and good luck getting the role you want
