Taking damage does give you rage, but it's not enough rage to reflect, switch stances, intercept, and hamstring. A macro to swap out the 2h for shield is viable, but slow. Most warriors would rather go for the pummel if they are using 2h. FWIW, I have reflected a fully trinketed pyroblast back on a mage and seen it hit him for around 3000 damage, he STILL won.
Exactly, which is why this is best used for instances tanking. My guess is the boss would be immune. LOL
