Clash-of-clans – Troops walking out on me

When you are attacked, several things happen:

• You lose resources, depending on how much the attacker "destroys". If the attacker destroys everything, you can lose up to a maximum of 50% of Elixir/Gold in your collectors, 100% of Elixir/Gold in your Town Hall, and 10-20% of Elixir/Gold in your storage containers depending on your Town Hall level. You also lose 75% of Dark Elixir in your collectors, 5-10% of loot in your Clan Castle and 4-6% of Dark Elixir in your storages This is a worst case, and can be significantly less if the opponent is higher level than you, or does not fully succeed in destroying your buildings.
• You lose trophies, depending on how much the attacker "destroys" and also the relative amounts of trophies you and the attacker have. Attackers get 1/3 of potential trophies for each star they receive. Potential trophies are more if the attacker started with less trophies than you, and are fewer if the attacker started with more trophies than you.
• Your buildings are not actually destroyed, even when the opponent "destroys" them. Buildings regenerate after attacks.
• Troops in your Army Camp do not participate. Troops in your Clan's Castle will fight if any enemy troop is deployed in its radius.
• There is a range of who can attack you. However, this is based on the number of trophies you have. This makes it possible for high level players to attack you. These players have just simply purposefully lost a bunch of trophies so they can "pick on" low level players. Bear in mind though that pairing is random, so in order for a higher level attacker to attack, they have to be randomly paired with you. Note this does not apply if you've previously attacked them, since they have a "revenge" option.

A strategy that works for me is the standard giant-healer attack. Find and take out the air defense close to you by distracting the defenses with a couple troops, use a few wall-breakers to break the wall. Then send as many giants as needed to take out the air defense. Then you can deploy the healer and the giants will destroy most of the defenses with nearly no trouble, provided no air defenses. However, problems can often arise with this strategy. The wall breakers could die, the giants could switch to a different target. In the event of this, I find a healing spell as a good way to keep the giants alive until it is safe to deploy the healer. Place it in the spot the giants will go, or in the center of them if there attacking. For clan castle troops, a few troops will do the job. Usually a lightning spell can quickly kill a mob of archers/barbarians. Even if the air defense is still there, deploy the healer as far from it as possible. YOU NEED THOSE GIANTS! Anyway, once the defenses somewhere are taken out, deploy archers or barbs to take out some stuff. If something is out of range of a defense, shoot it down. I have used this strategy for a month, and it is very effective. I have not lost one battle since I started doing this. Understand this works differently for everyone. Hope this helps.
