All decent ideas
The problem I generally see with warrior talents are the ability to choose between damage and damage+stuns in multiple tiers. Bladestorm and Dragon Roar have to be extremely potent to overcome the added utility of Shockwave's stun - alternately Shockwave has to deal non-trivial damage to compensate for the lesser damage it deals compared to its competitors.
In actuality, we're comparing Apples to Oranges - but we're comparing all the Oranges on Apple metrics, and all the Apples on Orange metrics - and Blizzard is seemingly unwilling to recognize the conflict. The same thing is true for Stormbolt in PvP. Bloodbath has to kill people to compensate for the loss of Avatars root+snare break and superior damage cooldown, Stormbolt has to do sufficient damage to not suck on the damage metric, and yet also provides a stun which the others don't.
If they want to make those tiers into damage tiers, that's fine - pick different situations in which the talents should excel and stick to it - but tacking on utility or CC breaks into those tiers makes the whole balance of it wonky.
Warriors have always been in a precarious position in PvP though - I hope they get a proper overhaul in 6.0 - because they deserve it. They are still struggling with mechanics that were awkward in Vanilla.
Actually after the Deep Wounds debuff, Arms passed Fury in single target DPS - and is now doing above average. Keep in mind the Affliction and Demonology parses are still bugged/being worked on as of this post - so they're obviously simming in way below what they actually do.

I'm not saying a damage nerf is necessarily the way to go - but the argument that it can't be done because of PvE isn't valid.
