I would agree OP, but they shifted their stance. Allied races are added post discovery and that makes the most sense. Like did it make sense for DKs to be trusted immediately at the start? Or Demon hunters? They were the enemy not even days before. Monks made sense because they simply introduced trainers so it was feasible they sent trainers out.
Tech got a huge boost with a new energy source with BfA. Going into the next expac with tinkers isn't a huge jump.
If they keep their old philosophy, it'll be necromancers based off Diablo and wotlk. If not, it'll be tinkers.
With like a 1% chance of dark rangers.
