Parry not stunning the opponent

I haven’t seen if this has been posted on already, but it’s yet another very significant and regularly occurring bug. Parry is only stunning the opponent on maybe half of my attempts now. The parry procs, but no stun. I have it on video, but here is a screen shot. This is a big one.. and needs fixing ASAP. I don’t understand how there is so consistently so many bugs with every update. Especially on something as basic as parry.
This particular fight was on 3.1 of the monthly uncollected quest.

1. You have a debuff on you, Masacre reduces DAA by 50%(I think) for each debuff. That means the parry will show, but not Proc.
2. You need to read about Challenger Rating. Your opponent has a MUCH higher CR than you, lowering your ability to proc abilities(think of it like hidden AAR that happens before the fight).
2. You are correct about CR not effecting parry, except the duration due to decreased stats. But I didn’t say anything about PI
