Sacrier's Sacrifice doesn't count AT buffs

The description for the card state that it deals damage equal to the sacrificed minion's AT to the target, however this does not currently include any AT buffs that are active on the sacrificed minion (I used it on a buffed Moloch with 5AT and only dealt 1 damage, much to my displeasure). Since the card doesn't stipulate that AT buffs aren't counted, I'm led to believe this is a bug or oversight?
