Its expensive to get anywhere as far as leveling up your guys. Yeah dont have to pay, but that's where the developers of this game get you. You would be waiting months or years to level up anything on this game to get any real progress. Once you finally get to level and it's all done and I'm talking about leveling for everything. You dont get major results. All that waiting for little boost in something. You want to get real results spend lots of money. These developers ought to ashamed.
