However when you attack a mob you automatically face (this is set as default unless you manually changed it). So in that sense you technically are "facing" a mob. An interesting thing that I noticed is when I spin the mobs in BCT 4. I am not locking on and I know for a fact that at times the enemy is perpendicular or greater in angle, yet I still can parry. Yes it is auto attacks and yes we all know spinning them reduces their attack rate but this is what I see. Then again with so much going on with proper pulls and top tier aggro management I could just be seeing things. I will have to test this out on low lvl mobs as the parry rate is much higher on them w/o using any buffs.
