I think you are putting too many fancy words into the problem.
Queues are balloons. If you put more air in than you are taking out, they grow until they pop. As utilisation grows (ie as the input volume of air starts to match the output) it takes much longer to get rid of the backlog.
This means that any traffic anomalies that would otherwise be hidden by the queue are instantly amplified.
If all you care about is engineering intuition, you can use any number of metaphors. I'm talking about what it takes to understand queues mathematically and prove correct results about them, rather than incorrect results.
