First off i will find and post what im talking about later since im at work but i saw this yesterday and never had time to ask about it, but it was an interview with blizzard where they were asking about future classes for Dracthyr. It was one of those pop up ads on the side of the page when you open a new tab as a suggestion from Google.
I cant remember exactly how it was phrased but it was more or less the interviewer asking about where they are making classes more available to races and asked something along the lines of will we see dracthyr warriors later on. And the blizzard guy didnt say no but answered by saying that dracthyr and evokers were made for each other, but did say something about the other dragon people we see in the starting area. So maybe there is hope for people who wanted the more dragonkin looking people
But as said before i will find this article when i get off work so it doesnt sound like im talking out my butt
