So IT (which should be your first ability to use in 99% of the cases) was the most obvious choice for that.
GoD never really did anything more than making things easier, while not providing more threat or something than another glyph choice would bring.
IT doesn't really need to be nerfed. Only really bad tanks (or new ones in bad gear) would need to spam it.
But if something like the old S3D
VottW/LB/BSh spec should arise, which had maxed out survivability but more than subpar threat, would become viable through IT machinegunning, THEN we have a problem that should be nerfed.
Edit: Just to stress this again, if your tanking abilities are anything worth, you shouldn't be loosing threat after 1-2 ITs. And then you can return to the standard priority system. Aside from the first 10-20 seconds DK threat was always fine.
