Ugh - I hope we get some dev confirmation on this. I know there had been a dev statement or patch note somewhere that stated we could turn in local leves on any class. I don't remember seeing any further notes changing that - but I also didn't pay any attention when I turned in my leves. I did notice I got less exp than expected on some turn ins though. I frequently head to a camp to turn in my local leves in my fighting gear, not my crafting gear. Until this is clarified, I supposed I will have to change jobs before each turn in for now.
