Okay... so you're saying the Light's priority is to avoid losses. I understand that to mean avoiding losses on neutral creatures. Or are you planning to resurrect in the final battle? Good luck; unprotected League units will fall 10% faster, and that's all you'll achieve.
Really?
If the Retribution strike, which gives +12 to attack, only guaranteed the death of 7th-level creatures...
And in general, does Chaos often kill "a dozen" creatures? I rarely see that happen.
Unless it's with companions on giant maps.
But even there, you can win by just pumping up your magic skills and not taking Chaos magic.

Just so you know, I once played on a huge map against someone, playing as Sylvan, against the League.
I had 16 Crystal Dragonlings.
I attacked a Castle...
The enemy had a Stronghold + Lucky Sorcerer + 2 League Castles + dragons were a suitable element. Shock wiped out 14.
So, talking about "dozens" of 7th-level creatures is clearly an overstatement.
First, a well-developed 20th-level Necromancer can reliably take out 8 7th-level creatures at a time. Second, the battle tactics depend directly on the Necromancer's opponent. In some cases, Chaos magic won't be needed at all; Irresistible Magic will be enough. In other cases, if the opponent is, say, a Rune Priest, it will be much better not to give up Chaos magic spells. It's practically impossible to consider all possible variations, and trying to fit every event into the same scheme is more than foolish. You need to take all factors into account, including the player himself; only then will something worthwhile come out of it.
