Dynamic Queue Bot Lane.
Playing with 3-4 friends you tend to duo bot with one of your friends, but that 5th person can rain on your parade and add toxicity on pre-pick. Because ADCing with a random OR a support is not nearly as fun as playing with your buddy you're in a call with. My recommendation is when there is a preset bot lane (per say Player 1 is ADC and Player 2 is Support in your party) you should automatically get it, instead of playing with a random on the most synergy reliant role.
