Sunder Armor: NEGATIVE Threat?

I have this theory that Sunder Armor actually results in negative threat when your group/raid consists of >>>melee<<< DPS.


When the tank uses the ability Sunder Armor, they are generating a low amount of threat. For the sake of example, we will say it generates 300 threat.

Now, let's say a rogue in dpsing the mob the tank is tanking. That Sunder Armor directly increases the amount of dps the rogue puts out, and therefore directly increases the amount of threat the rogue generates.

My theory is that the rogue generates more threat as a result of a Sunder Armor than the tank does.

Think of it this way (purely for example's sake):
Tank generates +300 threat.
Rogue generates +400 threat.
In this example, the tank generated NEGATIVE threat in relation to the melee DPS.


Here is an example for you visual learners....
Tank Threat Pre-Sunder
====================
Rogue Threat Pre-Sunder
==========
Tank Threat Post-Sunder
========================
Rogue Threat Post-Sunder
=================

As you can see, the tank had twice as much threat as the rogue before the sunder, but now only has about 25% more threat even though the tank's threat also increased.

I have not run any tests on this theory with actual numbers but if anyone has, let me know!

P.S. I am well aware that the armor debuff also affects the threat of the tank's attacks, however I don't believe that this small benefit can be compared to the benefit that melee dps receives.
