So, how about patch 5.2 as of the most recent PTR. Second Wind is currently back up to 3% healing a tick (still lower rage gen), Defensive Stance is nerfed for non-tanks but should remain exactly the same for tank specced warriors, Impending Victory got a mild buff to its healing (up to 15% from its current 10%), Slam is still slightly buffed, Taste for Blood is still completely redesigned (and I will talk about it, having gotten the chance to play around with it some) and frankly kind of weird, but none of these changes are massive ones aside from that Taste for Blood change and its repercussions.
As we discussed before, most of the changes seem aimed either at Vengeance and its scaling, or PvP issues like everyone taking Shockwave for a stun on a 20 second cooldown. The Taste for Blood change is obviously also rooted in PvP, but one of the more interesting consequences of that change is that it makes Heroic Strike even less desirable for arms than it already was. For fury, the Bloodsurge change is clearly aimed at getting us to want to use Wild Strike more and Heroic Strike less since it's more rewarding to pool rage and throw off a couple of HS after a Colossus Smash than it is to wait for a Bloodsurge proc and use a low damage Wild Strike, and squeezing in three of them just doesn't fit the rotation most times.
Still, there are definitely things to talk about with this PTR and warriors. A lot of them aren't implemented yet is the problem.
