Back in the day when I worked customer support for Microsoft products, we had metrics that we strove to meet. Things like "customer waits no more than two minutes on hold" etc.
If Turbine tracks things like "Time ticket created" vs "Time ticket addressed" there should be a way to make an estimated wait time when you submit a ticket (Number of tickets in the queue times average wait time).
This will give us an idea if it is worth waiting in a quest for help, or if we should quit out and try running something else.
