Unlike roosh's Starcraft, having your village totally destroyed isn't a big deal in Clash of Clans. Even if someone completely destroys your village during a raid and levels it to the ground, after their 3 minute raid is over, it's all immediately rebuilt back for free. Over and over again. You never lose buildings, walls, or anything else, they're only destroyed temporarily during a player's raid, then they're restored.
The only thing you can lose from a raid is:
50% of the loot sitting in your your collectors (your mines and pumps)
20% of the loot sitting in your storage vaults. (they're more secure)
Any traps that were set off you have to repay to reset.
Everything else, all the buildings they spent all that time destroying, just get rebuilt back for free after their raid is over. No big deal. Every building you build will keep regenerating forever, no matter how many times it's attacked and knocked down raid after raid. So the game is about protecting your loot (the only thing that can be stolen), and the best way to protect loot is spending it on buildings, walls and upgrades, which are permanent (and can never be stolen).
While new accounts are given a free 3 day shield, you also get a free 12 hour shield anytime someone destroys 40% of your village or destroys your townhall, which is a whole lot of hours that no one can attack and loot you during. If they 90% your village, the shield is increased to 16 hours. So a lot of farmers will put the walls and defenses around their storages, and leave the townhall someplace easy to attack. Someone comes along, destroys the townhall for a tiny bit of resources with a single barbarian, and you get a free 12 hour shield. Good trade.
The worst thing that can happen is one person comes in and steals some of your loot... but they never destroy enough to trigger a shield, and then another person raids you more ...getting you in a chain. A chain of people each stealing a little will quickly drain off a lot more loot that one person who takes 20% and gives you a 12-16 hour shield, locking out anyone else from attacking you and giving your collectors time to fill up.
CoC's main interest is that it gives you more control than it seems at first: You control what troops are put out, when, and where. Once players get good at understanding how the different troops move because of their different AI, there's some actual strategy and skill for such a silly phone app game, and they will get in a rhythm of raiding over and over again as fast as they can build their next army. You can't be raided while you're actively logged in the game, so a lot of players will raid until they can afford something new, empty their storages buying it, and then log off. With no loot left, most people will "next" it for something else.
It's also very easy in CoC to spend more building an army than you get back in loot from raiding with it, giving you a
Pyrrhic Victory that leaves you bankrupt for a while. Worst case you spend everything on your army, get no loot at all, can't rebuild a new one, and have to wait the painful hours for your collectors to gather enough you can build troops again. The Next button is important, letting you skip over loot poor villages that will make you bankrupt if you waste your expensive army attacking them.
