It is actually against the rules to join beginner servers on an alt. This used to be dealt with by the ToriAgents then by the GameMasters - but its no longer part of the GM job, I used to do it occasionally but Im pretty sure I was the only one.
This is just some information on the issue, Im not sure what solutions would be possible, as bringing back the toriagents or giving the job back to the GMs dont sit quite right. Bringing back a not really necessary staff group / throwing more work on arguably the most work intensive staff job already
