@AliEf What we do get for sure, are armour skins (already part of the Foundation rewards and Kickstarter packs).
Besides that depending on how it will look at the end, having the option to turn off items like cape, head and feet gear would be welcomed by me, as it gives you more choices to your looks in general and I can't imagine a Erwydra with a helmet on right now. Beastmen in general should be able to walk barefeeted anyway.
@GamerSeuss is right, about having the option to identify if a player is wearing light, medium or heavy armour. Armour skins will change depending on the "underlying" armour. How this will work if the player is wearing a mix of different types, I have no clue yet. Most likely based on the body piece or the most average type of your chosen mix.
