Hello there. I think it's not hard to agree that Guardian would look amazing in a fully armored outfit. Please atleast consider these options, or consider making her a completely new one.

Black Knight: Ossa Cerberi:

Personally, it seems that Guardian outfit's have been lacking in.. the pants- section. Please give us the ability to actually use proper armor on Guardian. The Ossa cerberi is an excellent example. ♥️

I agree 100%!

Guardian and Corsair are the only classes that I know of that doesn't have any real armour outfits and I can't picture Corsair having heavy armour. Guardian on the other hand is one of those classes that definitely should have heavily armored outfits. I'm honestly suprised that she doesn't even have one considering she's a tank and a Guardian. The class name itself should give away what she should be wearing. I know that that they didn't go with a "Paladin" themed type of Guardian like in GW2 but a Guardian of the wilds type of theme. The thing is she's a tank using a shield and battle axe or a poleaxe to fight and that itself is a type of Guardian that should have at least one heavily armored outfit.

Also, pretty much all her main outfits are revealing. I don't mind that and there are some that I really like but I would also like a badass nordic warrior with heavy armour and fur that is not so skimpy

I wouldn't mind Ossa Cerberi being available to Guardians because after all her nordic sisters Valkyrie and Drakania have them

If they do decide to make a completely new one then here are some illustration examples that I have found that I would love to see on a Guardian:

First to fourth image is the closest representation to the theme.
The Fourth one would also look great with the Valkyrie
5th one doesn't fit the theme but the armour with the Halberd would look cool on the Guardian
