I think the Drachthyr looks more like lizards than dragons, to be honest. It won't hurt if they were a bit bulkier but since they are a mostly ranged class they didn't want to empathize their physical prowess.

Still, what is a dragon if they can't crush stuff with their bare claws?

I could argue female Dracthryr are not appealing but whoever still plays Blizzard games expecting anything remotely sexy is wasting their time.
