Again, I'm not asking what you use it for, I'm asking why people think it actually was implemented the way it is.
My answer stands.

Castrum and Praetorium should not be in DR:Mentor, as there are plenty of people running those through DR:MainScenario for rewards that DR:Mentor doesn't even come close to providing. In this regard, the implementation is clearly wrong.

As for extreme trials, the only arguable justification for putting extreme trials in DR:Mentor is so the new people can be told what an extreme trial is so that they stop queuing unprepared. It's still not a mentor's responsibility to know the entire fight choreography from four role perspectives so that they can fix people's mistakes, nevermind that there's always one or two people who refuse to listen to any feedback anyway.
