I've been playing this game for about a month, I'm league 12 and haven't spent a penny while playing. Yes, you can pay if you like and get a bit ahead of other players but you'll certainly have to pay much more to make solid advantage out of it. You'll get much further when you stop whining about how P2W the game is and instead of it try to understand the principles of the game. There are also weekend events that could win you lots of iteresting stuff.
