There are multiple spots on the last flag on Weathertop, Amon Sul itself, where players can hide in tunnels but still be considered on the flag. This is unintuitive for even some existing players, given that I've seen attackers camp hidden location the whole capture cycle and win.
Similarly unintuitive locations exist with climbing to the ceiling of Gothmog's tent using trapdoors on Black Gate, hiding in interior of Helms Gatehouse, and using constructor wood to climb on top of domes at main gate on Minas Tirith (Which was a problem as far back as v2, before barriers were placed to prevent it).
Move to positions shown in screenshot when relevant flag is capturable (utilizing constructor wood/ladders where necessary, before destroying them behind you if you so choose), sneak to hide, and cause confusion or irritation of enemy players. As shown by the "Your banner flies over <Flag Name>" messages, these spots do count towards capturing flag by attacking team.
