Again the leftovers fall into a stat that isn't that desirable at least with arcane build str compliments, unlike STR build where arcane doesn't really help. You also get a higher crit chance with this build. However, Harbinger is generally agreed to be stronger than Necromancer so this helps out.
These builds also note that if you're going for a STR or Arcane build with these you're going to end up getting some undesirables as well.
