A new tank stance to fit Dark Knight better

Add an Incress to parry while in grit nuf said.

It really is that simple.

I'd like to see it grant 20%. That is only a 4% reduction in damage on average, and you cannot parry everything anyways.

I think a change to Reprisal should also be done inconjuntion with that. Increase the Duration to 40s// OR lower the cool down to 20s and increase the duration to 30s. The idea is to be able to keep the debuff up consistantly.
Alternatively, remove the Parry requirement and change it to grant -Xs CD every parry. If X is 2s, then 5 Parrys would reduce the CD to the debuff's Duration.
