If people were afking, the afking would be around the clock, 24/7. Except the queues are only at peak times.

These aren't afkers, these are active players. The server is just that crowded.

Sure, SE should fix afk-avoidance exploits. They should fix a lot of things. But the afkers aren't causing the issue, stop telling yourself that. It's overpopulation that's causing the issue.
