If using Revenge in your rotation, War Academy is about 15% below Cruelty in terms of DPS per talent point. Cruelty is better, but only by a small margin. Deep Wounds still remains much better (almost double) per point than either one of them.
However, if you drop Revenge from your rotation with War Academy and use Devastate instead, you gain a significant amount of TPS just from dropping Revenge (about the same value as both points in Hold the Line or all 3 points in Cruelty) but War Academy then adds more TPS per talent point than Hold the Line, Shockwave weaving, or Cruelty by about 10-20%.
If you are single-target tanking and do not need the AoE splash from Improved Revenge, this then frees up two points in the primary Protection tree for use in utility talents or increased Rage flow from Shield Spec. Also, as War Academy buffs Victory Rush it makes Impending Victory much less of a TPS loss should you choose to take it in addition to more reliable as you are replacing Revenge with Devastate. (I don't love Impending Victory, but this route does make it better.)
My personal feeling is that Revenge needs a serious buff, but with these changes it actually seems sensible to still maintain War Academy and drop Improved Revenge and Revenge from your rotation unless you are rage-starved. If you do this, War Academy is actually only about 10-15% worse than it was when it affected Heroic Strike even with a Heroic Strike frequency of 90%.
Example numbers (assume that without Improved Revenge you don't use Revenge):
(baseline), no Revenge: 8623 DPS
2/2 Improved Revenge: 8693 DPS
2/2 Improved Revenge, 2/2 Cruelty: 8893 DPS
3/3 War Academy, 2/2 Improved Revenge: 8932 DPS
3/3 War Academy: 8991 DPS
3/3 War Academy, 2/2 Cruelty: 9191 DPS
3/3 War Academy, 3/3 Deep Wounds: 9614 DPS
3/3 War Academy, 3/3 Deep Wounds, 2/2 Cruelty: 9854 DPS
