I'd like to address something from the comments of my previous post. In response to my questioning of Imp Ret Aura's worthiness of two talent points, BigFire wrote:
If you're a PVE retribution paladin, the improved rebtibution aura is not for you, but for the tank, especially for a protection paladin in your raid. I'm a protection paladin, and for the most part, I put up improved devotion aura for the secondary effect of 6% extra heal. With your better scaled retribution aura, I'll do a whole tons of threat.Now, I agree with him on principle - in a group setting, the points are not for me. BUT, the claim that a prot paladin would do "a ton more threat" seems... off. I thought I just got finished with a rambling rant about how the feedback damage is larger than if the ret paladin did not talent into Imp Ret Aura, but the numbers after avoidance and boss attack speed were figured in would end up smaller than expected.
So, let's take a closer look. Imp Ret Aura, as I last stated, is probably about ~30 DPS (rough estimate) at a T7 level of gearing and raid buffs vs a single target boss with a 2.0-2.5 swing and a tank with T7 levels of avoidance. If you take that as a given, you're looking at ~60 TPS (rounded up) for a prot paladin from Imp Ret Aura.
This will only add threat if the mobs are all ready attacking the prot paladin. But so will Holy Shield, Consecration, Hammer of the Righteous, and ticking stacks of Seal of Vengeance. The additional TPS from the aura will not help in picking up mobs, it will only help in cementing a threat lead. Are any prot paladins that hard up for AoE threat in this day and age? Are any tanks at all (aside from feral druids, they have issues with Swipe, so I've heard) hard up for AoE threat? Because, in truth, we're talking about less than 60 TPS, and I don't think that many tanks are having much trouble holding things in place nowadays.
Where else could the points go? Divine Purpose for situational stun removal, on the ret paladin, a healer, a tank, whatever. Vindication to chop down trash clears a smidge. Guardian's Favor to protect a clothie more often on initial mob pick-up - this is a pro-active way to let the tank get aggro instead of the passive Imp Ret Aura, which would only increase the aggro lead slightly and only once the tank has control. All three of those talents are two-pointers that have situational effectiveness, and might possibly be worth more than 30 DPS (or 60 TPS for the tank).
Weigh in with your opinion. Provide me with a reasoned argument why I should stay invested in this talent. And if you can quantify the benefits of Divine Purpose, Guardian's Favor, and/or Vindication for comparison purposes, I'll love you forever.
