Normal Luk Versus Lukless; When do they surpass?

As a LUK mage (I started in 2005 when it was the only real option.) the difference is not that huge. A Lukless mage who is the same level as myself only does 2k (average) more damage. Personally I don't think it's such a big deal, I like the fancy armor I get to wear and I'm fine with doing 2k less on my spells.
