It doesn't say buy what you feel like buying it says assess what type of player you are and make informed decisions based on that. No guide should 100% tell you what to do with your own money.
This wasn't written for you anyway as you own the game.
You don`t have to be offended by what I said though, I just criticized the topic.
Another question, how many new users we have on coh2.org that do not own the game?
I always had the impression people bought the game first and then looked at forums
