okay on a levequest, I dont know if you saw it but the game gives you a warning for switching classes, right so why is that important, I have a second video i am trying to upload that confirms you get a great Def, on lower level from 80 to 130+ and I was fighting Lv 20 monsters while I was lv 15. Also this can be done for others just not a CNJ/GlD, but well there are endless possibilities right.
