All great points and thank you for discussing what I have actually written.
I wouldnt argue that having more parry isnt great. If all the encounters were the same and each opponent was predictibale then maybe I would have re-speced, or if my team felt it was worth it after we discussed it then I would have changed.
And again im not making the case that the build I had was better than everything else, just helpful for what I did. Many games it was tagging multiple people with hamstring and rend, reapply as needed to free up certain people so its not always a prolonged engagement with one person. So placing additional damge on multiple people that I wasnt actively engaged with just adds to the collective damage that our team would do on targets that were not necessarily the focus or most important threat. If the rogues are waiting for all the dots and bleeds to gall of so they can restealth or if the collective damage is enough that thebperson takes a little more time to bandage be fore re-engaging then it gives us the extra time of having an advantage somewhere else on the bg.
Once I draw focus and start taking multiple targets then its a matter of my healers keeping me up because no amount of parry would save me.
If I was only doing pugs then I would likely get the extra parry.
If our flag carriers wasnt available, then i'd play my level 10 with def gear, at least until it was changed.
