Paladin 2p is going for Hand of Reckoning instead of Righteous Defense, which is good; RD is almost never used by comparison any more.
Paladin 4p explicitly reduces the forbearance penalty.
Druid 4P is now reducing the cooldown of Barkskin by 12 seconds (was 10% more barkskinny goodness)
Warrior 4P is now reducing the cooldown of shield block by 10 seconds (was 20).
While I miss the thought of being ridiculously OP, it was pretty clear with some basic math that 30% barkskin wasn't going to see the light of day. Though I'll be surprised if 90-second divine protection for paladins lasts.
