For me, the War Room was a pre-education on a lot of different topics. My IM experience started by joining the WF, then buying some not so great WSO's then joining the WarRoom and finally finding BHW.
I never made a dime following any advice in the WF but I make a good living from a few ideas found in BHW.
The WarRoom is the garage sale of WSO's- instead of paying money, they give it to you for free in the hopes of getting you to sign up for their list or gaining thanks for being charitable. Mostly it's where they put their stuff that they can no longer sell.
Now with that in mind, it's a decent place to find ideas (not methods) for things and to get some basic info. Why is it not a great place for methods? Because most of what they give away there is either outdated or fairly saturated. It also is a great place to get some things that you can rehash into your own stuff.
Occasionally there is something good- like a decent app or report or list- but it's not nearly the "goldmine" I thought it was once I really started to learn/understand IM.
