I understand the historical need that PP filled, but that's all but gone now that blessings are simplified and imp talents only exist for two of the four. It only takes a moment to figure out blessing when there's more that one pally... and judgements. Here's how it goes down when I'm tanking:

[me] "Hey I have imp might, I'll bless might/wisdon and judge wisdom, you get kings and light"
[other pally] "ok"

Of course, I give myself (and therefore the other pally) sanc.

If it's a holy pally, I let him take wisdom and I do kings for the mana users, while he does kings on the others. The only time there's an issue is hybrids that want all three buffs, but frankly they just have to suck it up and take what they get.

That's why I have no intent of adding PP support to Cork. It's a lot of complicated code that's rendered unnecessary by taking a moment to decide on judgements... which can usually be done before everyone's been summoned.

I much prefer the UI of Paladin Buffer and it talks with PP users as well. It's basically PP but with a better interface, IMO.

PallyPower, while it might not be the best or flashiest addon, is the golden standard for Paladin buffs, and as a raid leader I love it and expect all paladins in my raids to have it. It's also very useful for Emalon pugs and such when the paladins can assign one to set the settings for everyone else, and get it done quickly and efficiently. With the addition of auras, I would say PallyPower is a must have for every raiding paladin.
