So, that's not bag of rats? I can ask my allies to knock non-minion kobolds unconscious, and eat one a day? Doesn't seem like any DM I know would let that fly.
But you can't oath, quarry, curse, divine challenge, divine mettle, divine strength, lay on hands, ardent vow, inspiring word, shake it off, rousing words, etc. It's a very high cost, especially at higher levels when you have a plethora of other minor actions you may want to use from item powers, to class features, to utility powers. Very few builds have the luxury of spare minor actions. And ending your turn in a form that doesn't even allow you to make opportunity attacks or immediate action attacks is certainly another hindrance.
Will do, thanks.
