I have been fiddling for months with my Dark Elves, trying all kinds of Sorceress and scroll-caddy combos, before just saying "screw it"!
By my calculation, I was spending 2-300 points to get a level of combat effectivness that was totally random and roughly on par to a repeater bolt-thrower.
I've instead gone no-magic and rely soley on a mounted Ring of Hotek (so I can get him where I most need him) and the occasional key unit with Null Talismans, and poured all the leftover points into more offense. Its been working well for me.
What are your thoughts on the no-magic option and are there certian armies it workes better for, or not at all?
