On the whole the devs did a great job with the pots in general. They provide a boost in an area with a hidden drawback in another. Unfortunately as we all know the Int pots are the exception to this. a -50% fortification is a massive drawback that stops almost everyone from using it. If the song of recklesness is dangerous this pot is far more so. I agree that there should be a signifcant drawback to each of these pots but believe that this one should definitely be a priority.
Even a -2 to all physical stats would be better than this.
btw a read by a dev would be very nice on this one...
