Chaos is actually better than light for Necromancers, as it provides a lot of magic.
And if you focus 100% on being a warrior, light won't help you much. I've tested it; if you develop warfare, you don't get much magic, and the spells last for only 2-3 turns and don't help much. But, for example, darkness can be very useful in 3 turns, even with low magic, and summoning is simply a great ability. You can create hordes of neutral creatures with minimal magic and troops, so light is a magic that I personally would develop last.
