Most warriors tend to take Glyphs of Blocking, Revenge, and Heroic Strike, which negates the less-rage downside pretty easily. As Wroar has said, and our personal experience Dungeon Fighter gold reflects this, Devastate just is not worth the GCD when either SS or Revenge is up. Since Devastate is then used rather sparingly, and you definitely do not want to skip a Revenge or SS proc just to dump some rage, you can use it as well as Heroic Strike when your rage permits it. It really does work.
However, we will disagree with Wroar's evaluation of Vigilance. We are more than happy to lose 2% crit from Cruelty to snag two very awesome abilities. Maybe the numbers work out differently, but we like the idea of gaining threat while stunned/MCd/otherwise incapacitated. We are assuming that would work, if not, we have some points to move.
