DW Tanking, and Why it SUCKS

I can't take it anymore!!!!

Everywhere I look, DK's are trying to DW tank, and it makes no frickin sense! So much potential lost on stupidity...

Let's examine the basic principles of DK tanking, and why DW sucks ass. I'll try to esplain the best I can.


Why Anyone would want to DW Tank: Myths/Beliefs
1.) It Looks Cool
2.) Stats are better on 2x 1H's vs. 2H
3.) Greater TPS (threat generation)


Ok--so now you have some reasoning behind actually equipping 2x 1-handers to tank. Now, for some edu-muh-cation:

Threat:
A DK's threat (other than DnD) is based on damage. The higher the damage, the higher the TPS (threat per second). A DK's strike damage (as well as all other classes) is normalized, and based on weapon speed. Melee weapons are broken down into 3 categories: 1.7, 2.4, and 3.3--the slower the weapon, the greater the damage, thus the more threat is generated.

Now, with the inclusion of Threat of Thessarian into the Frost tree, it is semi-plausable to create a DW tank-spec. I say semi plausable, because maximizing DW costs an additional 4 points vs. its 2H predecessor. 4 points that would have to be removed from either Bladed Armor, or other beneficial points in the unholy tree. With Nerves of Cold steel, and Threat of Thessarian maxed, theoretically, strike damage would be up to par with a 2H build.

Now, there are 2 problems with this:
1.) Hit Cap
2.) Strike Normalization

Obtaining 8% hit cap for a 2H tanking build is easy. DW is another story. At 13% hit rating, DW still misses a large chunk of the time. Missing causes problems, not only with rotations and runes, but also for generating threat (especially since all Tanking 1H's are fast, thus the damage created is on par with daggers). DW tanks also need a solid amount of expertise to avoid parry-gibs. The expertise cap for DW is 64 skill (500 rating)--obtaining this number is quite difficult. If not capped, then DW tanking with 2x 1.6 speed weapons actually increases the chance of being parry-gibbed by 3.75x...

On average, dual wielding tanking weapons add an extra 2% avoidance (but lose out on AP stats like strength, which translates into damage), however, the amount of attacks more than doubles, thus increasing the chance to be parried as such. Boss parry-haste can stack multiple times, therefore attacks against you have the chance to come faster and faster. This causes more damage more quickly, and places added stress on the healers; in endgame it can ultimately cause a wipe (think steelbreaker).

Conclusion
Trading out a strong 2-hander for 2x 1-handers may lead to additional defense skill and avoidance, but really neglects the basic principles of DK tanking. Be able to hit the boss, be able to hit the boss hard (TPS), and don't be parried. DW tanking begins at a disadvantage in all of these areas. So while it may look cool, and may be functional for trivial things like heroics and SM runs (at lvl 80), it is not at all acceptable for endgame raiding.

Everyone knows you don't go full retard.
