staying in hay is glitching...you can see the people outside but they cant see you...so no
It's becouse the third person camera.
Really.
If you stand close to the end of a wall/building, so can you see out. While others can't see you.
Yeah sure, you can't shoot arrows from there without moving out in the open but;
If you haven't realized on most siege maps or town maps so is it a piece of cake for 2handers to get kills purely by standing next to the corner and wait for someone to come and kill them.
Due to they are prepared and can see the enemy coming, while the attackers don't see them.
