Just hit 70 last night so I can't tell you about instances, but I've soloed everything including the 5-man HEs and solo instances all the way through spinward without dying using this super sekrit combo, so I'll let you guys in on it. You wanna go Justice tree, even without the capstone working you'll still be untouchable…
I'd like to point out that the justice capstone feat isn't entirely broken on protection paladins, just mostly. While I have seen no cooldown reduction or damage increase, I have had instant divine call refills on encounter use with popup text "vengeful judge," so the feat is only mostly broken and useless
I can say with some certainty that Ice Knife will add three stacks of the debuff to targets but only add one stack of the buff to you, but I don't know about other dailies.
I'm finding, at least in PvP, that my powers are starting to go into cooldown even if I don't get them off once they're interrupted mid cast. Had this happen with chill strike for sure, and I have a suspicion it happened with entangling force, but was a little distracted when I got interrupted then. Really irritating to…
