Thanks for getting back to me with this information. I was indeed looking at it from a Rage point of view and I had noticed that same thing. In instances/boss fights I generally have plenty of rage, but find myself rage starved while questing. I was considering dumping Deflection in favor of Unbridled Wrath, hoping I would gain from the slightly decreased avoidance and increased rage from melee. I'm still up in the air about it and wonder if anyone here has tried it. However, when I look at profiles I find that just about everyone has 5 points in Deflection.
At any rate, I really appreciate you taking the time to comment on my question. Thanks for your input!
Sorry, your question had scrolled off the chat while I did a quick search. I wasn't able to find any numbers as to additional rage from unbridled wrath. If you're looking at it from a tanking perspective for more rage, rage isn't really as much of an issue while tanking anymore. I dumped the rage gain talents I had back in 3.0 (Anger Management and Imp Bloodrage) and I still find myself capped at 100 rage on boss fights. If you're having rage problems on trash and aren't having survivability problems, just pull more trash. Thunderclap and Shockwave make it so we can hold as many trash as we can survive, and doing so will speed up runs a ton.
