No, I don't like it. Because I see laziness in everything about it.
New races should have a new animation rig. Dracthyr dragon form reuses old rig of male succubus / female nathrezim. Mortal form reuses male belf and female human rigs.
New classes should have 3 specs to appeal to larger audience, not 2 specs because "being creative is hard".
Dracthyr dragon model should wear player's armor, otherwise it is a glorified druid shapeshifting.
The overall art direction of Dracthyr looks like one big pandering to furry audience, with all that colorful mess of design. Limiting new class to only this new race is kinda dumb, because it creates a strict connection between new gameplay and a very specific aesthetics.

Every time I see something like that I remember that Blizzard is small indie company that cannot afford new animations, because they require a lot of resources.
