Happen this last hours. Not going common if he was abusing this bug or not. As the other TC say.

 

Not enough evidence here to really say anything. Either I am missing something, or you are claiming you should have received more AP than what you did from defeating this player.

AP gains from player kills are affected by several things: Damage you deal to the player versus damage dealt to them by the environment (eg, other monsters, players, etc), The player's abyss rank, your abyss rank (at least in retail), and probably some other factors as well.

Since your chat log does not indicate the rank of the player you killed, as well as other information, we cannot justify an investigation into your issue.
