Death Knight T12 Tank Set 2p Bonus not working

[darkmaster2133]

Describe the bug
Death Knight T12 Tank Set 2p Bonus not working.
It is supposed to make attacks behave as if the target has two diseases active, but it does not.

To Reproduce
Steps to reproduce the behavior:

1. Apply Tank 2p on Frost DPS
2. Remove Plague Strike from rotation
3. Sim
4. Compare Obliterate damage to if you were casting Plague Strike

Expected behavior
Obliterate damage should not change

@darkmaster2133 it's currently not adding on top of diseases. Until we find proof that it adds on top as instead of a default 2 baseline if less than 2 are present it should probably stay as is. (Neither EJ forums, nor SimC implemented/tested this bonus)

I couldn't find any proof that it will add on top of other diseases as in; 2/3 + 2 (from 2P), since that would make it incredibly strong for Frost (~800DPS) and Unholy (~1500DPS).

Closing it for now until we can determine the actual behavior from PTR.
