Protection spec warriors, did you enjoy being able to charge out of roots and snares to get back to the boss fast? Well, thanks to PvP, you won't be able to do that anymore. What else won't you be able to do? Well, if you've been stacking block value in PvE content, first off, I kind of don't get you. Seriously, except for very specific gimmicky fights, why would you stack block value? (I said value, not rating, and I also said gimmicky fights so don't bring up Heroic Anub) But if you have been... perhaps you have a block value set for totally destroying adds or something... then get ready for a Shield Slam nerf. They're 'testing that one internally' which, if you remember how horrible the Rage Normalization changes went in early BC, always works.
Honestly, neither of these are huge gamebreakers. I liked that Warbringer cleared roots and snares for me when I was tanking, and I barely even noticed it in PvP: it was like a free self-cast Hand of Freedom. As for nerfing Shield Slam, well, like I said I don't stack block value so a lower block value cap on the ability wouldn't really affect me. Irritate me? Yes, it will do that. But it isn't a game breaker either. Of course, since as the commenters mentioned yesterday prot PvP warriors don't stack shield block value at all (I know you guys don't read my posts, Blizzard, but if for some reason someone is, look at all that ArP. Look at all that lack of block value. It is ArP that drives the prot PvP damage machine. ArP, not block value. Just thought I'd mention that) then I fail to see any point to the change either.
So there we have it: Warbringer gets changed and Shield Slam might get changed which is like taking a club away from a guy who is shooting people.
