Do the locations match up with the classes?

chatting with some friends led to the subject of associating the classes with the different 5 regions. I was thinking barbarian for fractured peaks, druid and scosglen, sorc in dry steppes, with rouge in kehjistan, and Necro for the swamps in hawezar. has anything been put out about this? did I miss some lore? (I went through campaign pretty quick)
