New Troop....Gy the Piper
One thing that I like very much about Boom Beach is the flare. This allows you to guide the troops to where you want to attack. Here is my idea for the Clash version.
New troop called Gy the Piper. This troop has no attack abilities and should have a decent hitpoint value. A user would set it down and then give it a path to tread (either with a swipe screen or second hit like the barb king). Other troops would follow Gy the Piper until he is dead. Following troops would still attack the things they are custom to attacking (golums=defense, goblins=resources, etc.). Once the piper is dead the other troops revert to attacking at random. The piper can be upgraded, adding more hitpoints to prolong life.
Tell me what you think!
