I like what you guys did with Ground Powder and PH range, so I have an Idea about walls: A wall thats height adjustable, what does that mean? It means that you can use your wall two diferent ways. Way 1: Normal high just like curent walls, no diference. Way 2: The wall can get higher at a push of a button. So the advantages and disadvantages are those: Advantages For Defender: No troups can get or shoot over higher wall (inc. Sky Raider), higher walls has lesser health and can be a little easier to destroy than low high walls. Advantages For Attacker: If the defender has higher walls, Cannons and Bunkers can't shoot over them at attacker, only Mortars,Towers and GP can whoot over high walls. The reason for this? More strategy involved, more fun and diverse way of attacking and defending.
