Heres a change in 1.12 that was made after the release of PTRs. Perhaps this will give new angles to the 'Does Lifetap cause threat?' debates I've been seeing as of late.
Life Tap: This spell now benefits from effects which increase your spell damage. At rank 3 and above, the base amount of health lost and mana gained will increase by 80% of your bonus spell damage effects. Talents and items can further modify those values. Rank 1 and 2 receive reduced effect.

Cheer!!!
