I've been through a lot of this already. I'll make these points for now.
Boob plate doesn't exist in the real world, at least not in the sense that it's a good idea. Armour should deflect weapons, not focus them towards your sternum. But whatever, I think we all feel comfortable letting this go.

I don't like morphing armour. I prefer to have control of the aesthetic myself. But if you really want to put effort into giving each piece of armour a unique feel for each race, then fine. Though it really makes me worry. D:OS had only a handful of different outfits, and by adding 3 new races, they're going to have 4 times as much work (a lot of which will probably wasted, because elves and dwarves are biased towards certain classes anyway). I'm definitely not optimistic for a lot of variety here. I expect elves are going to look pretty much interchangeable with each other.

Anyway, if I give my elf (boy or girl) heavy armour, as a minimum I want it to look like the elf is wearing heavy armour.
