I have a friend who explicitly wanted to be a RDM and immediately uninstalled his free trial the instant I told him he had to get to level 50 and finish the 2.0 story first.

This is a thing I called out when the HW jobs were gated behind the entire 2.x line.

I'll restate what I said then: when you advertise a new expansion and put the new jobs front and center (which you should!), people are going to want to play them. That doesn't seem super unreasonable to me. They want to play what you showed them. But then they have an ever-growing mass of content between them and the job they're actually interested in playing. There's no reason for it, let the people play the cool jobs you're dangling in front of them.
