From everything I have seen and tested myself Warrior dps in general is pretty solid in 5.4. I do not like though how boring Arms is, and how lopsided the dps is from single target to the crazy AoE/cleave it does. Fury is in a good place if you factor in the single target boost we get if you use SB instead of bloodbath for Fury, especially TG.
As TG using SB with the CDR trinket, SB lines up perfectly every time with CS and the damage is truely nice to see as far as single target goes. During the burst off the pull I am seeing 2 Million crits from SB. If you are to go Arms for ANY AoE/Cleave fight for example Dark Shaman, Heroic Immersus, etc. Arms will pull ahead of all other specs if you do the rotation correctly which is mind numbing how easy it is.
As it stands right now, Warrior DPS is solid as far as where we will place in our raid groups if we were to play to optimization. IMO if we were to see some sort of Fury buff in any way, it would just be icing on the cake.
Dont forget how crit works for us as fury :P Crit + weapon dmg is basically the reason why we're scaling like we are :P It's a known fact that warriors scale insanely with gear - weak early xpack and usually veeery strong late xpack. Blizz tried to fix it for MoP, but it would seem that they failed horribly.
Arms on the other hand scales HORRIBLY.
you seems to forget that we were scaling great because of infinite rage which we dont have anymore so dont expect us to be insane anymore.
We are looking great in 5.4 honestly. No more doom and gloom from me. Our aoe is great (and more usable than 5.2), survivability easier with changes and single target slightly higher. Not to mention RPPM leaving is pulling everyone else basically but us down.
