Yeah, because people prefer groups. regardless, that wasnt my point. and now you are moving the goalpost from the previous premade definition (full team) to now 5 mans. If grouping was 3 mans, youd call 5 3 mans premades too. It never ends.
It is not a grand mystery and nothing is broken. It was not broken in the beginning, people just naturally gravitate into groups. it didnt just decide to “stop working” a month after the change. It is also influenced by the extremely abysmal population of sod pvp players queueing up (barely anyone)
the premade change algorithm carried over to era servers, and solo q is fine there. Though the change should have never carried over and it likely will never be removed there. Thanks throwers/quitters/afkers!
