A couple of us tried IM Moors/Muscle Mages, hmm, longer than a year ago. The farthest we got was a dlvl 2 clear, excepting Butcher. Stairtrappers is the forte of no low level mage, I'll tell ya.
This forum's more or less dead now, but I appreciate your post. You certainly know a great deal more about IM than do I. 
Oh, here's a picture from the Moorish frontier:

And the Moorish battlechant:
"We pluck our bows as we'd play a harp
And play the song of death!
When ye sees our arrows comin'
You'll suck in your last breath!
An' yer 'ead will roll across the floor
Full of little twigs!
After all we're mages
Can't lift much more than sprigs!
We roam along
Mow down the throngs
To the lone last beast!
And though he turns his tail to rrruuuuunnn
We won't stop when he yells 'Cease!'
Won't stop when he yells 'Cease!'
Wont stooop when he yyyyeeells 'Ceeeeease!'"
