The revenge waves make the last battle more interesting, just as the titan does. Each revenge wave pushes you back to your own castle, so you need to fall back and fight your way to the enemy's castle again! Without it the last battle would be a... normal one..

dont be mad if you get back to the start though, it also goes backwards :D
