I was just reading the preview article for the next CP and it mentioned pairing Thoren with FtW for easy power gainz.

I was under the impression that, while using FtW, you still had to beat your oppents attackers to actually consider yourself the winner. Am I wrong? I dont believe that "you cannot lose" means that you automatically win, but the article suggests otherwise

The articles aren't always correct, although since Pipes has taken to writing them, they usually are!

In this case, he may have been referring to the fact that your opponent tends to "Chump challenge" (a low str challenge" since they know they can't win, in order to burn through For the Watch!'s effect. At that point, the effort in winning the challenge becomes very easy. The reason this hasn't been a big deal so far is that NW isn't heavily rewarded for winning challenges on defence (with the exception of one event, and a little renown/insight) - but Thoren changes that!
