Theorically, a nation with easy access to Death and/or Fire (especially Death since its research boosting artefact comes earlier) might get away with some Drain. A Rainbow Mage would help as well, since Drain would be almost irrelevant for her.

In actual practice, I would be hard put to find a situation where 40 points (or even 80) would be good enough to justify the trouble of taking Drain. Perhaps with a special game where you have fewer than 500 points, but that would be an experimental situation, so.
