The lack of showing helmets on Viera/Hrothgar is a design choice. They could have made their heads less "unique" and just treat them like the other races, but they chose not to to give us more options (what those options are we don't know yet).
They could do "butt sliders", but they have chosen not to because it would be too much work for what they get out of it (seriously, we don't need butt sliders, that's a rather niche thing).
They could have made a healer but CHOSE not to in favor of balancing the other healers.
What I think you are confusing, OP, are choices vs limitations. There aren't any real limitations other than TIME. And it's how they CHOOSE to spend their TIME, not that they are limited by the engine/code.
