I think of it this way, if you have bought a bar for $70, and still play this game after more than 2 years it isn't that bad of a deal. Yea sure its an ios game but consider the amount of hours you have in it (non afkers) and then compare to how many hours you have on other console games costing about the same, halo, cod, battlefield. If you choose to buy any other guns it's your choice, but if your new and you plan on playing this game for more than a year than investing $70 isn't really a rip off if you get a years worth of enjoyment from it.
But thatd just my view on it and whether or not you agree with it the day bar was released was the beginning of guns priced the way they are. I dont plan on releasing anything more expensive during my time as GA to at least stop things becoming more expensive than it already is
