Hi,
I'm sure there are more people who encountered this issue few times, but I didn't find any discussions on this topic here. The ticket I raised came back as "useless" from Kabam customer service.
Basically, when you parry in Battlegrounds, or stun in any ways, the duration of the stun is so ridiculously small that you are Not able to heavy the opponent. Please exclude all possible abilities and masteries aside. I run maxed stun and stupefy masteries, and when I run 5/5 limber, my opponents successfully use AA against me.
So, what could be the issue? It was so frustrating to lose matches, especially in BGs tournaments, when you have clear advantageous matchup but just can't heavy the opponent.
