Can we just remove 4-mans or make a toggling option to be grouped with them
Of all the premades (2-3-4, not 5-man because then you are in it) where do you get the most toxic and most annoying games? 4-mans. It is always the solo's fault for a loss, they _never _ have any say in votes/bans (unless they are in a ban picking spot), and are usually abandoned by the premade to fend for themselves while they help each other (and are not always successful at doing so).
Also because you are with a 4-man you most likely will face at least another 4-man if not a 5-man, and this means you already are at a communication disadvantage before the game even started. Please just make queues solo and 2-3-5-man premades only. Or have a separate option for the 4-man like a toggle option to allow you to be matched with them as a solo.
