Let's start with the relevant sections from the patchnotes:
Warrior
Battle Shout now lasts 1 hour and no longer generates Rage.
Berserker Rage no longer generates Rage or increases Physical damage dealt.
Berserker Stance has been removed.
Cleave has been removed.
Commanding Shout now lasts 1 hour and no longer generates Rage.
Demoralizing Banner has been removed.
Hamstring is now a passive ability that causes Mortal Strike, Bloodthirst, Revenge, and Raging Blow to also reduce the target’s movement speed by 50% for 15 seconds.
Rallying Cry is no longer available to Protection Warriors.
Recklessness is now available only to Fury and Arms Warriors.
Skull Banner has been removed.
Throw has been removed.
Thunder Clap is no longer available to Fury Warriors.
Whirlwind is now available only to Fury Warriors.Warrior
Charge now Roots the target (instead of stunning). The Root effect does not share a Diminishing Return with other Roots.
Warbringer now causes Charge to stun the target for 1.5 sec instead of rooting it.
Disarm has been removed.
Intimidating Shout now has a 6 sec duration in PvP (down from 8 sec).Protection: Vengeance changes and Protection Mastery changes to compensate; Riposte updated.Active mitigation has worked very well as a tanking model. So, moving forward we want to keep the amount of Dodge and Parry on tanks on the low side. This helps prevent encounters from causing very spiky damage on tanks, which generally isn't much fun. Dodge and Parry gains from Strength and Agility are being reduced to help accomplish this. Additionally, items in Warlords of Draenor will not have Dodge or Parry on them as a stat. Some Dodge and Parry can still be gained through class-specific effects.
The amount of Dodge gained per point of Agility has been reduced by 25%.
The amount of Parry gained per point of Strength has been reduced by 25%.
Vengeance has been removed and replaced with a new passive ability, Resolve.
Resolve: Increases your healing and absorption done to yourself, based on Stamina and damage taken (before avoidance and mitigation) in the last 10 seconds.
Warrior
Mastery: Critical Block now also passively increases Attack Power by 12% (percentage increased by Mastery), in addition to its current effects.A few things I'm concerned about so far:Riposte has been redesigned.
Riposte gives the Warrior +100% to Parry chance until they Parry an attack after getting a critical strike with an Auto Attack.
-Being a warrior tank myself, I really hate losing 100% of my raid utility. They'd have to balance the tanks at level 100 pretty damn close to avoid guilds stacking the fotm class.
-With Dodge and Parry mostly gone, how are they gonna rework Revenge to stay viable and keep RPM about the same? The Riposte redesign helps a little bit but you're still gonna see less revenge procs.
-Here we go again with the charge change, I thought the community had been pretty clear about that?
Update: There's more, wall of text inc:
Edit: Draenor Perks, you get these while leveling from 90 to 100 (apparently in a random order that changes per player):Warrior
We wanted to fix a few problems with Warriors. First, we still weren't happy with Arms' rotation (and neither were many players), so we've made some more changes, primarily through cutting abilities (see Ability Pruning above).
As with other classes, we wanted to reduce cooldown stacking. Cutting Skull Banner did a ton to help that across the whole game. But for Warriors specifically, we needed to make further changes, including merging some of the personal benefit of Skull Banner back into Recklessness. Also, to make up for Throw being removed, we modified Heroic Throw to be more frequently usable.
Recklessness now increases Critical Strike chance by 15% (down from 30%) and increases Critical Strike damage by 10% (up from 0%).
Shattering Throw no longer reduces the armor of the target; it only does damage and breaks immunities.
It also is no longer learned via any specialization, but instead through a new Major Glyph, Glyph of Shattering Throw.
Heroic Throw now has a 6-second cooldown (down from 30 seconds), but now has a 15 yard minimum range.
Haste has long been a problematic stat for Warriors, usually being of little value. As part of our commitment to ensuring all secondary stats are valuable (except Bonus Armor for non-tanks and Spirit for non-healers, of course), we're making a significant change to Warriors, to ensure that Haste has strong, competitive value. We're giving all Warriors a new passive, which lets haste affect their global cooldown, and the cooldowns of their very-short-cooldown rotational abilities.
Headlong Rush is a new passive ability for Warriors:
Headlong Rush: Haste reduces global cooldown and the cooldowns of Mortal Strike, Bloodthirst, Shield Slam, and Thunder Clap.
Protection Warriors have received a few notable changes. First, we removed Dodge and Parry from gear, and expect Protection Warriors to value Haste and Crit as important secondary stats. In order to achieve that, we made Riposte give defensive value to Crits. The aforementioned Headlong Rush also helps for valuing Haste.
Riposte has been redesigned.
Riposte gives the Warrior +100% to Parry chance until they Parry an attack after getting a critical strike with an Auto Attack.
A few Warrior Talents also were in need of revision. First, Second Wind was problematic; it was sometimes too weak, and sometimes too strong. We chose to change it from a passive health regeneration effect to the new Leech effect, so that low-health Warriors have to maintain combat in order to benefit, instead of kiting, hiding, or otherwise playing defensively. For the level-60 and level-90 Talent rows, certain combinations were proving problematic. We decided that Stormbolt would better compete with Shockwave and Dragon Roar, and that Bladestorm would better compete with Avatar and Bloodbath, so swapped Stormbolt and Bladestorm's positions.
Second Wind no longer directly heals the Warrior while active. Instead, Second Wind grants the Warrior 10% Leech while active, which causes the Warrior to heal for 10% of all damage and healing done by the Warrior while active.
Bladestorm is now a level-90 Talent, swapping places with Stormbolt.
Bladestorm no longer allows use of Shouts while active. It does still allow the use of Taunt, Enraged Regeneration, Shield Wall, and Last Stand.
Stormbolt is now a level-60 Talent, swapping places with Bladestorm.
Fury Warriors are receiving updates to spell alerts to improve usability.
Bloodsurge’s spell alert has moved to the top slot instead of the left/right slots.
Raging Blow now has a spell alert on the left and right slots.
With the introduction of one of the level-100 Warrior Talents, which deals Fire damage, we also expanded Enrage to affect all damage, not just Physical damage.
Enrage now increases all damage (up from only Physical damage).
Mastery: Unshackled Fury (Fury) now increases all damage (up from only Physical damage).
We're also making a change to the design of Deep Wounds, to try to limit is effectiveness in PvP, without hurting its effectiveness in PvE.
Deep Wounds now lasts 15 seconds, or until the target is healed to full health.
