Not really, it can work in that fashion if you don't plan on it. I wouldn't teleport a SC into the midst of 300+ troops without a force to back it regardless of my intent. Though that is my playstyle. On the other hand, if a mage is scripted to cast Raise Skeletons it will more than likely keep casting it. Thus providing you with more than enough hands to kill those paralzyed creatures.

Of course; this is supposed to be an AAR, not Norfleet's reasons why he has had issues with Astral Shield and/or Wyrms because of his playstyle.
