Non warrior-ish armor
Braham’s armor looks pretty nice. It’s more like cloth armor in that it doesn’t really have any metal plates (aside from the horns on the shoulders and helm)
Aetherblade and Zodiac armor from the gemstore
It can also depend on what your race is so just take a look at the armor gallery and see what you like. http://wiki.guildwars2.com/wiki/Human_male_heavy_armor
From the looks of it the least protective sets are:
- Twilight Arbor
- Durmand Priory
- Draconic
- Aetherblade
- Braham’s
- Flamewrath
- Zodiac
In my opinion the only sets that really seem “roguish” would be the Order of Whispers and Twilight Armor. Both of which have a more leathery look to them. You can also try mixing and matching different skins if you have them.
The Kodan leg armor is a good “lightly armored” set. It only has a small amount of metal on it with the rest being cloth. Both that and draconic look really cool when you fight because of how it flaps around.
