Contained in the link is a little flavor text for the archetype, its features, and one homebrewed feat made for the archetype.
It is made to emulate these guys: Roman Soldiers
Roman soldiers would use their large shields to hide their weapons from their opponent's view. This allowed them to attack from above their shield, bellow their shield, or anywhere along the side of their shield, making it very hard for an opponent to guard against them because the shield blocked their view of the weapon until right before the weapon became a danger.
I chose Rogue for this archetype due to the sneak attack mechanics. It screamed "smart fighter" to me, the same way this fighting style screamed "smart fighter."
Please tell me your feedback guys. Do you think this archetype is too strong? Does it give up too little or too much?
