Considering the turn in this thread, I have to ask the question:

How often do DM's actually use the INT or WIS of the monster when designing an adventure - or when the monster is in battle??

It certainly seems like it is pretty rare.

I hear about players that are able to have fighters singlehandedly slay 100 enemies. I hear about small groups of characters able to waltz into a dragon's lair and slay it without so much as a near-casualty. I hear stories of small groups of players able to stave off attacks of huge armies - with only stuff that might help MacGuyver.

Have things crapped out so badly that DM's don't consider the INT/WIS/experience of the monsters they use any more? If so, it truly saddens me.
