Swizzle's Fury Warrior Guide (3.3.5a)

Specialization (spec)
Armored to the Teeth (3/3) - Essential for the attack power boost gained. You wear plate therefore you'll have a good amount of armor making the bonus nice.
Cruelty (5/5) - Extra critical strike rating in a MUST at lower levels. Continue reading to find out why.
Unbridled Wrath (5/5) - Keeps you from going completely rage hungry during fights.
Improved Cleave (3/3) - Increases the bonus damage on Cleave to 120%. This is nice versus MULTIPLE ENEMIES.
Dual Wield Specialization (5/5) - Needed to keep your rage up. Your off-hand weapon generates most of your rage via white (normal) attacks.
Precision (3/3) - Needed to keep you at the hit cap. Having this skill allows you to get 5% hit, and then focus on other needed stats. The hit cap for MDPS is 8%
Death Wish (1/1)- ABSOLUTELY NEEDED. This is a solid 30% INCREASE on your damage done on a 3 minute cool down.
Improved Berserker Rage (2/2) - Mainly used at the beginning of the fight to gain the 20 rage so you have the ability to use your cool downs at the beginning of a fight.
Flurry (5/5) - MUST HAVE FOR FURY WARRIORS. This is a 25% increase attack speed for your next 3 hits. At 30% critical chance, Flurry is up 100% of the time. This is why you need to have Cruelty (5/5).
Intensify Rage (3/3) - This reduces the cool down on your main skills, giving them more up time.
Bloodthirst (1/1) - MUST HAVE FOR FURY WARRIORS. This is your main damaging skill other than Whirlwind.
Improved Whirlwind (2/2) - This is a MUST. It increases your Whirlwind's damage by a further 20%!
Improved Berserker Stance (5/5) - This is a MUST. It increases your base strength by a further 20% and reduces your threat generation by 10% while in stance.
Bloodsurge (3/3) - This is needed to allow you to have instant Slams which is another DPS increase.
Rampage (1/1) - Gives you and all party/raid members another 5% critical hit chance.
Unending Fury (5/5) - MUST HAVE FOR FURY WARRIORS. This increases the damage of your main skills by another 10%.
Titan's Grip (1/1) - MUST HAVE FOR FURY WARRIORS. This is just the bread and butter of the Fury specialization, don't go without it.
Improved Rend (2/2) - This increases your Rend's tick damage by another further 20%!
Improved Heroic Strike (3/3) - This lowers the rage cost of your Heroic Strike from 15 down to 12.
Tactical Mastery (2/3) - This allows you to switch to Battle Stance and still have enough rage to Rend your target.
Iron Will (3/3) - This shortens the time STUN and CHARM effects have upon you by 20%.
Impale (2/2) - This increases the critical strike damage of your bonus abilities by another 20%. (Bloodthirst)
Deep Wounds (3/3) - Causes your critical strikes to make the target bleed for 48% of your weapons average damage.
Two Handed Specialization (3/3) - Increases melee damage done by 6% with two-handed weapons.




Rotation (Skill Order)
Opening
The VERY first skills you use before you even begin a boss fight are very crucial to how much DPS you`ll be pulling during the fight. Here is the opening to your rotation;
Bloodrage -> Berserker Rage -> Recklessness -> Death Wish
KEEP IN MIND, YOU USE THESE RIGHT BEFORE YOU START ATTACKING THE BOSS.

Main Rotation
Your main rotation will alternate between 2 different priority lists depending on how many targets are around you/attacking you.

Your single target ROTATION and PRIORITY is as follows;
Bloodthirst -> Whirlwind -> Slam -> Heroic Strike when above 50 rage.

Your multi-target ROTATION and PRIORITY is as follows;
Whirlwind -> Bloodthirst -> Slam -> Cleave when above 50 rage.

Keep in mind that you WILL have dead spaces in your rotation (times where all your skills are on cool down). This is where the Improved Rend (2/2) will come in.
To add Rend to your rotation will take time and practice, but will end up increasing your overall DPS by another good bit. The trick is to be able to stance dance to Battle Stance, use Rend, and then go back to Berserker Stance and continue your rotation. Note that you have LIMITED TIME to do this. The goal is to be able to pull a Rend off WITHIN the cool down time of Bloodthirst and Whirlwind so by the time you're back in Berserker Stance, Bloodthirst and Whirlwind are off cool down.
You can also use Heroic Throw as a filler to fill in the dead space when possible.


Stats and Caps
As a Fury warrior, you have some benchmarks and caps to reach so you can deal damage to your full potential. The priority of these stats/caps is as follows;
1. Hit cap (8%)
2. 4000 Attack Power
3. 1400 Armour Penetration (100%)
4. Strength

As a fresh level 80 warrior, your first priority is to reach the hit cap for PvE. This cap is at 8% hit. Keep in mind that you also have Precision (3/3) which gives you another 3% hit chance. With that 3% hit, you only need another 5% hit chance (5+3=8).
Your second priority is to have a base of 4000 attack power (No buffs or anything). You can start gemming ArP before you reach 4000 AP, but you won't notice much of a DPS increase until you reach 4000 AP.
Your third priority is 1400 armour penetration (100%). Once you have your 4000 base attack power, you're going to want to start gemming/stacking ArP. This will increase your damage substantially although you will not really notice a big difference until about 35-40% ArP. PLEASE NOTE, THIS IS PROBABLY THE HARDEST CAP TO REACH AS A WARRIOR! IT WILL TAKE TIME!
Lastly, the stat you will want to start stacking once you have 100% armour penetration is strength. Keep in mind that you want to stay above 1400 ArP while stacking strength so you only gain DPS and not lose any. Don't be afraid to play around with your gem set-up as once you are this far, most of your ArP will come from the actual pieces of gear itself!
