The part I disagree with in the above is simply if you don't have a creative space to really express how you want your character to be like.
I understand that resources are limited, but there was a clear design choice to go for twig armor instead of badass full bark-plate ala some Sylvari Armor in Guild Wars 2.
That is a decision Larion and their artists made, so if they have to work a bit harder to create additional art assets to provide some actual "protective" looking elf armor for both sexes, that is their own doing and they should take the time to create a variety to satisfy people like you and I who WOULD like to make a protected looking elf if we wish to.
I do strongly disagree that "harking back to old RPGs" is at all an excuse to not provide a variety of representations to choose from.
We have pixel art games that are throw back as well, namely Stardew Valley, that are made on a fraction of a budget and they still manage to allow exceptional amount of freedom in your character's expression of their gender. You can literally play a trans character if you so wish by selecting the opposite gender's clothing, you can marry who you wish, and the game provides options to fully cater to essentially anyone.
Its 2016, and there really is not a valid "rational" for why twig armor can pass for "the only option for heavy armor" on a character, of either gender. If its a neat option, sure, but if its the default and exclusive option? Hell no.
Games are a medium. They are a creation born of a creative process. Sometimes it is good practice to evaluate your process through multiple lenses to see how others may view your finished product. Currently, I can understand how MANY potential customers would view the current elf models and armor options as "pandering" where as we have other, wonderful models like the female dwarf and Lizard who have a great variety of options, poses, and are much more unique.
We really should expect better on the Elves. Their current models really don't convey how cool their culture is or really how distinct and unique their armor COULD look.
