Durin is a dragon! With literal wings. It only makes sense that he should be able to use them. Throughout the archon quest we have witnessed Durin express his latent ability to fly to his friends from Simulanka. At the end of his story quest, he proves his ability to fly. Yet, in the current game mechanics, Durin is unable to use his wings for gliding or mobility. 

In Genshin, there exist numerous four-star and five-star units that have enhanced mobility or even simple animation changes. Even Arlecchino has wings and uses them during her charged attack as mobility. In contrast, Durin, being a dragon, is a creature with literal wings on his back. It is both bewildering and disappointing that he does not use them. 

There are even other units that have mobility and/or special animations that are not Anemo or Natlanese. Such as Lauma, Skirk, Yelan, Hutao, Gaming, Kirara, and even Aino.. Many of which are four stars. Just a simple gliding animation should be a part of his kit already. Giving him a wind glider when he has wings is redundant and breaks the immersion of the world. 

Durin should have mobility or at the very least glide using his wings. It would make the game much more coherent and immersive. 

Please help me to convince the game developers to unlock Durin's wings. Thank you!
