Some of these prot warrior changes are...interesting? I didn't really expect them to change this much of the spec. I'm not going to paste them because mmoc's diff method is just terrible.
Revenge now costs 30 rage, 3s cooldown, parry or dodge makes it free.
Shield Block now costs 15 rage.
Tclap doubled in damage, generates 3 rage and has 30% chance to reset shield slam.
Best Served Cold moved up a few tiers to replace Ultimatum and does 5% increased damage for each target revenge hits, up to 5.
Devastator replaces the aforementioned, causes autoattacks to generate extra damage, generate 5 rage, and 30% chance to reset shield slam.
Revenge replaces Focused Rage in Vengeance.
Unless you HAVE to use revenges non-free, that seems like a ton of more rage for prot tanks.
Theorizing some more...Devastator probably replaces Devastate, so probably not much more extra rage actually.
