User blog comment:The Milkman/Why Expert Is Better/@comment-3455248-20110813162858

I started off with Normal in both single and multi, then switched to Expert. Now I try to use Expert all the time, except in the following situations:
 * Undead Overrun (it's co-op, so I use Normal "for the team" since I'm not quite as good with Expert)
 * If someone's harassing me and my Expert vengeance just isn't cutting it. :-)
