Wondering if anyone else has this issue.
Since Apr 27th before maintenance I have noticed my hits on bosses don't register right away.
The only thing I changed was I removed 1 addon, and added 1 addon.
I have since tested removing the addon and that doesn't change anything.
Its not a lag issue, I have more then enough lag experience to know the difference. The fights still smooth and quick. At first I thought it was that all my hits were getting parried (rogue rage), but the damage does come off eventually.
So for example my Wound Attack hit hits but does not show on the boss blood loss for say 5 secs then all the hits I have done in that 5 sec span come off the boss at once. Even stranger is the boss is dead .... but has HP still (see picture).
