Wall update

There should be an update where the walls can get taller, so Giants, and archers and some air troops are slowed down. For example, if there was a double wall then Giants would have to hit it for longer because the wall is taller, and reaches the Giants height.

Archers bows, could maybe get an upgrade so they shoot farther and higher.

Dragons would have no problem and neither would ballons, but maybe we could add an update where healers not only heal but do small minor damage to any building or troops they touch. So any other air troops, and walls which are stacked or double height.

On on that note, healers are useless if you get attacked and it comes out of the clan castle. That should be changed.
