TL;DR
Why the hell can't Evoker be the iconic Warcraft Dragons that we have spent the last 20 years growing up with?
Dragons have been represented very consistently over the last few decades of Warcraft lore. They have a humanoid Visage which they choose based on their identity but are truly capital D Dragons. Throughout the decades of Warcraft story, Dragon characters have accompanied us on adventures.
Yet when it comes time to actually implement playable Dragons in WoW, Dracthyr design seems to be based on compromises that never had to be made in the first place, and in my view is wasting years of established Dragon lore. If you were a fan of Chromie, Kalec, Alex, Wrathion, Ysera, Ebonhorn, Nefarian, Onyxia, Krasus, Azuregos, and you were looking forward to getting to play their role in WoW, Dracthyr Evoker is a huge disappointment.
It all seems predicated on this idea that players simply can't be regular Dragons... but why the f not? We can already mount Dragons, some even transform your character into a Dragon. I would argue that the Sandstone Drake is already a better implementation of a playable Dragon race/class than Dracthyr is. It is especially funny/sad because any random with Sandstone Drake can turn into a Dragon and fly their friends around but a Dracthyr Evoker can't.
The obvious solution: Just scrap Dracthyr humanoids completely. Recycle the Dragon-head customization for regular dragons. Pour customization options into the design of ACTUAL no compromise Dragons, and drop the fur suits. The heads and faces they have designed for the Dracthyr are not bad and can be salvaged. But the furaffinity-inspired scalies are
FUBAR.
Second, open up visage options to every race, just slap on some horns. So you can make your Female Gnome Evoker and RP as Chromie all the same. The Horns, and make-up, and scale-tattoos on the Human and Belf aren't bad, just expand those out to everyone.

Instead, the current design of the Dracthyr seems to be inspired by this kind of fantasy instead:
It is not too late to fix this mistake!
