I don't know what you mean by a "normal" battle (where your participation is undoubtedly required), but imagine this incredible fact: they use "Divine Power," the simplest first-level spell, and they use it much more often than "Divine Retribution." Yes, "Divine Power" is also very effective for necromancers, but, of course, they can also use "Divine Retribution"; they have plenty of magical power.
Well, now you've at least softened your stance a bit and are recommending the chaos I suggested; I hope that after some time, you will also be able to adequately assess the power of Light magic.
