Im hoping to compile various parry/block rates in FCoB. Parry vs trash mobs is pretty well dissected but parry rates seem to drop drastically in FCoB.

i130 shield and 595 parry.

3hrs of turn11 (don't ask)
32% block rate
11% parry rate

90min of turn12
28% block rate
8% parry rate

I will post more data as I complete more FCoB and I'm hoping others will chime in as well. I only thought to do this after looking over my t11 parse and noticing how low my parry rate was.
