First off, I’m talking major, new, “box feature” races, not allied races. I’m talking races that were announced as selling points of their expansions, blood elves, draenei, pandaren, goblin, worgen, kul tiran, zandalari.
That out of the way, dracthyr are the laziest new race in the history of the game.
Visage forms are reskins
And barely even reskins at that. They’re literally just a male blood elf and a human female. You can give them pointy ears and scaly bits but, as they stand now, they will never read as anything but male blood elves and human females. They sure as hell won’t read as a new race or even members of the same race. I’m sure there’s a lot of nice customizations but it doesn’t change that this not only is lazy but also looks lazy.
If you’re going to use barely altered existing races for the visage form then give us a few races to choose from for our visage form. If you want the visage form to be a new race, put in the work to make a new race.
Dragon form can’t use mogging
The effort can be put in to make current armor work on dracthry dragon form (though I admit helms could be a problem). Pandaren, draenei, and vulpera (and maybe someday worgen 
) have shown that tails aren’t impossible to make gear work with. Demon hunters have shown wings aren’t impossible to make gear work with. But, at the moment, it seems Blizz would rather not put in the effort. Instead we’ll only be able to mog belts, shoulders, and tabard. All other clothing options will be in the barber shop which means dragon form, the form most dracthyr players will be in the majority of the time, will have fewer mogging options than any other race or class outside of druid forms. There’s no way the barber shop will have as many clothing options as 18 years of gear, and how often do you think they’ll add new dracthyr clothing options to the barber shop, especially after the expansion ends?
The barber shop clothing options are fine, and it would be nice to keep that unique feature, but not putting in the effort to make mogging work on dragon form is going to be frustrating for players and more work down the line if you ever decide to fix it. Best to bite the bullet and make it work now.
Dragon form has only one body option
All the other playable races have two different body options to choose from. For those races the difference is male and female. Dracthyr don’t need to have male and female models but they should have two different model options. And, no, “slightly thicker torso options” doesn’t cut it. Let’s face it, making one body option for a race is both half the effort and half the choice. There’s really no way to pretend otherwise. And again, I’m sure there’s a lot of nifty cosmetic options, but that doesn’t change the fundamental one body problem.
Dragon form is a reskin too (or the incubus is a reskin of them, which is barely any better)
It appears the dracthyr dragon form is a reskin of the incubus warlock pet. If so, that means both the visage forms and the dragon form are reskins. An entirely reskinned race as a box feature is pretty, yeah, not great.
Now, it could be that the incubus is a reskinned dracthyr, but is that really any better? How would you feel as a worgen player if hunters had a reskinned worgen pet? What if mages had a reskinned draenei as their water elemental? I could be wrong, but I don’t think currently any class has a pet that’s just a reskin of a playable race. Until now, of course.
A reskinned warlock pet or warlocks have reskinned dracthyr, either way, not a good look. Frankly, a lazy look.
Bottom line, I like the concept of the dracthyr and I think Dragonflight has a lot of potential to be a lot of fun, but as it stands now, the dracthyr are underwhelming on some very fundamental levels. Here’s hoping that it’s still early days and they’ll put in the added effort to make them really great, or at least as good as any other box feature playable race from WoW’s past.
