1. Intro
With this build you can do 6-7k dps while tanking in green-blue gear, and much higher at top GS.

2. What do u need to make it work?
Nothing special actually. You need to have tank items enough to be a tank. But to make it work at its top potential - you need:
- GOOD tank items, because you'll be ~5-8% weaker than usual tank, so u need to compensate it with items
- DPS trinkets/ashen ring. Yep, strength, attack power, APR, hit, crit, haste procs etc.
- This item ... not necessary bit it makes everything better.
- This talent build ... yep, its 37/2/32, yep, it has no weapon specialisation, any normal player will say its some insane crap with no sence, but its not.
( Build with specialisation, in case if u dont have that dagger and will use some usual 1H mace/axe/sword )
- Glyphs: Glyph of Cleaving would be nice to have

3. How to make it work
Its simple. Just equip the tank gear, equip DPS trinkets, put a Revenge button on your action bar, find some boss/mobs. Start of in battle, cast sweeping strikes, charge, go into def stance, TC, and start cleaving like a crack head wielding a chain saw. Spam revenge and queue up cleaves for every attack. Use shield block, helps too, and other save skills.
The goal is to make your Revenge have 1 sec cooldown. It benefit from +AP, so all u need - equip items so it should be enough to NOT_DIE (def rating cap etc) and get the rest for attack power/crit/apr/hit.

4. So what do i loose
You are loosing:
- Critical block talent
- 2% strength, 5% stamina
- combat charge ablitiy

What are u getting:
+ insane dps boost, you can out-dps some DD in raid while tanking
+ reduced disarm duration
+ extra self-healing after stuns and CC
+ very usefull while leveling/farming/heroic runs
+ can be very usefull in raid, its like 1 extra DD in ur raid

PvP:
+ you are crushing every melee class in few seconds
- you suck vs mages/warlocks/etc, unless their pet will attack and trigger revenge (hint: use taunt)

5. Let me see how it works
Here is a simple demonstration how it works. NO BUFFS, no raid, only selfbuff, hitting random elite. Keep in mind this was made a ~year ago, this warrior is in Naxx content equip (3.0 patch):
Tank
in 3.3.5 my friend did 6k dps at 2.5k gs in Heroic run

AND THE LAST ONE - before saying its bad- try it, you'll see
