I've been asked about the feat Favored Power Attack, which is in both CWar and DragComp, so here's a ruling: Under normal circumstances, because DragComp was published after CWar, you would use the version of Favored Power Attack in DragComp. However, as a specific exception to this, you may use the version from CWar.

That feat wasn't OP and didn't need a nerf in the first place, so I don't mind throwing you this bone! If for some weird reason you find it more advantageous to use the DragComp version, you may, but you'll probably want to specify that you're doing so (and why you find that to be helpful). Judges are not to penalize solely based on choosing the CWar version or the DragComp version (though of course they may penalize or reward you for other choices you make surrounding this or any other build element).
