I'm not a big fan of those builds either. If I were to choose a build like that it would look something like this:

This is my main issue with this build that you have to spend those last 14 points for very little gain.
9 of those points can be spend in general to get sustained rage, hateful strikes and volcanic rage.
Another 4 points are probably best spend filling up devouring touch. Note that it's only the 1st and last point that give the most health tap. In any other desecration build with talisman mastery I'd say you can spend those 4 points better then 2.5% health tap but in this case there really isn't much else to spend them on.
No clue where to put that last point. Maybe fill out Hexers might or corrupt weapon even though both give a negligible return.
In my case build would end up looking something like this:

ps. I can't remember if touch of death can crit. If not then that point can be spend to fill up hexers might/corrupt weapon.
