Since this thread is about dracthyr appearance I'll talk about this in here.
Now that alpha is out and it is possible to see how armor actually looks like, I feel rather disapointed. You can't even mount in dracthyr form.
The armor you can put on in character creation (and I assume can change in barber) is very limited compared to actual selection of armors. I have seen some screenshots of these character creation armors and only one of them looks good. Basically it seems to me that this single armor is the only good set evokers can wear. That is unless the dragonflight content offers extra armors you can select or wear that looks good. It is still extremely limited.
Dracthyr looked fine enough and seems fine otherwise, but to basically separate it from the ability to transmog properly seems like big mistake.
I hope this will be fixed somehow.
