As you all know there are towers in AV. In these towers, at the top, are flags used to capture the tower. What you don't know is that these walls are not solid. You can attack people through the walls. What I getting at is that if you stand on one side of the hut on the top of the tower and a horde/ally rival is inside a melee character can attack them. While you cannot do any special moves like MS or sinister strike you can produce white damage still. I did this just now on an Ally and he just stood there taking the beating probably wondering wtf was going on. I'll add a screen shot when i can.
