If I am correct a player more than 3 lvls higher than you cant attack you. I learned from my mistakes of lvlíng up to fast and not paying as much attention to my power. I have been attacked by players with a mil or more power than myself with a lvl or 2 lower than me. This is just a suggestion that might get you in a little better situation....slow down your lvlíng and concentrate on your power. That will get you closer to the power of the players attacking you and if they keep lvlíng, they will get out of the atting range of you, making your game a bit more comfortable. That's what I have learned and worked on, have a long ways to go but it's getting better for me. Live and Learn
