Maybe they're saving this for legendary armors but I'd say they definitely need to make 2-3 variants of each armor category to represent each class. Apart from the helmet, I can perfectly imagine the medium armor on Ranger. Thief and Engineer? Absolutely not.
Also, ANet, PLEASE, take your time and design the Asura and Charr versions from scratch. It's like there's a certain conversation going on at ANet each time they design a new armor:
- Boss, what about the Charr versions?
- Well, we take the humanoid versions and - Pfft, make it bigger.
- Genius! *applause*
Daniel Dociu actually explained already, how Arena Net's philosophy is on playership minority-armors. Which amounted to "We put our focus on what people play most. We can't put as much time into Charr armors i.e. as we put into Human armors while 60% of our players are human."
Snake biting its own tail, I suppose - but if that's how it is, re-rolling human right now, despite costing me 500 g just to get the essentials (makeover kit, bag slots, transmutation splitters for legendaries) and the 3 dyes I already have, but want on my new character as well (charred/pyre/shiver sky).
I guess it keeps people busy to re-roll their characters to Humans, because other races are simply not deigned worthy of custom-fit armor models.
Not great, but alas, it is what it is.
