Yes, this is part of the fix for Marks ("Fix for Mark being consumed multiple times by multi-hit attacks").
Previous to this update, a mark would do damage per hit the character takes from an enemy attack, so if you had 3 marks on a character, the Assassin Golden Son would deal 3 x 3 = 9 mark hits (which at 12% each means it would do 108% of the character's Max HP as true damage). In addition to not being intended, it meant anyone who got to 7 power in PVP could kill the entire opposing team in 1 turn (even if you only got 2 marks, the amount of damage an Assassin Golden Son would do either finishes everyone else off anyways or softens them enough for other AoE'ers to finish).
Like you said, overpowered. Up to 36% of Max HP plus the massive chunk that Assassin Golden Sons does is still crazy dangerous if you pull off the same setup, though. It's just not a 7 power win-every-situation button.
I'm not sure. I'll follow up with the team and get back to you.
