tbh I find CoC and other "free-to-play" games as a cash grab. You progress slowly, and there's a leaderboard in your face showing who's better. Of course, you can get a little upgrade and get better, but it'll cost you. Fucking games like that become addicting and eventually you spend a bunch of money on it. Same thing with paying for multiplayer and DLC. It's pointless and jew-mongering.
