Lifedrain weapons may still be useful in very unusual cases (your ice devil or tartarian with heroic ability: increased strength), but for the vast majority of cases, they are completely worthless. Hell swords especially: 40 blood slaves and 10 fire gems for a -10 damage weapons? What was Zen smoking?

And even in those unusual cases, I'd bet that a standard sword of sharpness might still be the better choice given the cost difference. Basically Zen made lifedraining weapons the absolute worst weapons in the game. If he hated them so much, why not just get rid of them completely?

I think a more reasonable change, such as increasing the cost to 20 death gems/blood slaves and/or reducing the damage to 4-5 instead of 9 would have been the way to go. Zen's choice was far too extreme, especially when combined with Cherry's mod--armies will own the map under these settings, and will be impossible to stop without an army of your own. Perhaps that's what people want, though.
