The problem with making TBN a DPS gain instead of DPS neutral (or effectively neutral) as it is, is that it implicitly encourages you to eat more damage so you can put out more damage. Don't get me wrong, because I think that's pretty cool, but it doesn't work in a one-size-fits-all game where DRK has to play either MT or OT. I'll take TBN for what it is considering it's DPS neutral and also makes you laugh in the face of tankbusters.
Also, There is no "predicament" as far as tank balance goes. Yeah, DRK and WAR *might* need some extremely minor potency tweaks to bring them in line, but the difference in DPS between the weakest tank and the strongest tank amounts to roughly 2.5-3%, which is hilariously insignificant. There's also the fact that as Crit becomes more powerful, WAR's DPS will naturally increase as the patch cycle increases as the overwhelming bulk of it comes from their inner release window.
