Yeah it's a good solid couple of minutes of cruise to get there and back, which basically just results in the guard system being woefully underused. Which is sad. I can't see anyone really minding if it got moved into the ostnebel, except maybe the guy who was given the job of doing it.
I definitely agree. Compared with all the other guard systems I can think of, it's the only one where you have to go past or thoroughly around major hostile areas.
The only screenshot I had laying around is a bit older, so I think it was actually moved to the red dot area. My thought is to put it in one of the yellow dots, preferebly the Ostnebel one.
