That was trying to get people from the same server in a premade together. There were no “Cross Server Premade Ventrillos” i can guarantee you that.
You cannot equate people on 1 server trying to “3, 2 ,1 Queue!” of the old days to that raw scale of what was happening in Classic. The sheer massiveness of the amount of people queuing up and dropping queues was absolutely nothing like Vanilla.
