Been playing this for over an year and though it's a good game the balancing between p2p players and f2p players is way off the charts. As an example if you want to get the max rewards in an event, you have to spend around usd $1000 or more and that is not going to get you the top ranking in your server unless you play on a dead server. Why is the ranking important? Because there are events almost every month and the top 5 players can win a permanent HQ skin which gives you permanent attack buff
