I'm not a fan of pay to win at all and I think it kind of deteriorates the fun for everyone when that is part of the business model. There is a guy that lives nearby me, and older guy if you can believe that, who has NEVER paid for anything in CODM and he is always ranked really high and he also got one of the best guns just as a random drop or reward. Forgive my wording but I have never played the game at all.
