No way to advance unless you buy gems... – Clash of Clans Review

I'll admit that towards the beginning it is a fun game but once you get to be a high level with a max level town hall you can't advance after that unless you constantly buy shields which cost an absurd amount of gems. The reason you can't advance is because once you have a Max level town hall people can steal about 20 percent of everything you own which makes it impossible to replenish. Plus the people attacking you as you enter the crystal league are all 50 levels higher than you...is that fair?
