1) I agree with no monks. They shouldn't be monks.
2) I am sorry but I also agree with no Warlocks.
2a) Demonaics are more like Demon hunters than Warlocks, enslaving and becoming part demon. I am also really really really sorry about demonology spec they have been getting shafted since WoD.
2b) Zandalari Proper don't mess with fel magic. We fight a few Zandalari in Vol'dun that use fel magic. however you need to remember, any Zandalari in Vol'dun are exiles. They are not apart of Zandalari proper.
