I don't think you understood quite what I was getting at. Obviously there is a lot of overlap but in physics of the main subfields today plasma does not involve a lot of QM when compared to other fields that are almost exclusively QM. MHD is pretty much a classical model and it's working wel. It's clear that a QM model is necessary as your brought up, but there are few fields of research in physics today where you are able to seperate yourself so much from QM.
As my QM professor kept saying this semester, "If you hate this stuff, there's always plasmas."
