My Salisbury XP group last night had 8 players, 2 of which were necros. We discovered that they could pull single mobs with their powerdrain and never cause any additional mob aggro (BAF). This was tested on both the tomb raiders and skeletal centurions. Several other classes including a sorcerer tried to pull and always caused the normal BAF for our group size, with /challenge on or off.
I would consider this a major issue in PvE that trivializes combat and decreases grouping desirability of other classes.
