Feint has never given credit, to the best of my knowledge. Would be nice if it did for group hunting, since lots of other disablers do. Even though feint is less dramatic than say, 301, it's probably just as helpful.

I always feel bad when my buddy partner feints something and then I put an arrow in its eye. Instead, I'll wait for the feint, then lead off with an aimed shot at the leg or a Tonis bolt or something similarly non-deadly as a leadoff to not leave him high and dry.
