Teleports is not an abuse, that would imply that you're using it in a way it wasn't intended.
This game is designed as a pay-to-win - but if you're in a stable clan you can easily grow without spending any real money.
You will never become huge and you'll never have a very large army (several million), simply because there's a limit to your march and defending via shields or 'hiding' your troops won't be possible, but with a small payment of a couple of bucks ($4.99) a month and you can procure shields to stay shielded forever.
Yep this game is not for the casual player. If you don't pay to win you have to stay in a shield the whole time you play this game. Because of the teleporting ability without any cool-down (unlike every other game I played like this which DOES have a cool-down on ports). Being in a shield prevents you from taking part in the attacking events so if you want to enjoy all aspects of this game you need to spend to keep up with the bullies who just port, kill, port, kill and shield up themselves every few minutes.
