So, we kill Slate Dragon, Halfus does not lose Mortal Strike debuff. Kill Storm Rider, he keeps double attack speed. Call me retarded, but as far as I was aware he loses buffs when we kill the dragons, as before it was when you release. So... we /hugging them now? Anyone else have this happen? He also casts Paralysis just as/before a Drake dies and the buff stays on him during Paralysis and he keeps it when he's out of it.
