For most of us who are new or just arent at the PH11 range, some of us don't know what the New Defence designs look like such as the Voodoo Hut or the Academy new levels.
AC resembles the PH10 one in shape, but is diff colour. Bunkers have a pirate 'stamp' on top most other defenses are similar, but have the same stamp on them
Most of the people in my leaderboard (AUS) are just upgrading their ph or just don't have the maxed base
@Machop69 if you do a search on The Guild 'Midnight Rampage' a number of our members are well into their PH11 builds (including myself). Between us you should get a good idea on all the new defences and building.
