Most Nightblades ignore the ultimate Soul Siphon because it excludes healing the caster. I know it has been this way forever but in my opinion this should be considered a bug. There's absolutely no reason why it should heal everyone BUT the caster.
Looking at the skill itself, you can clearly see it doesn't state anything about not healing the caster, it simply says it "heals allies."
When looking at other healing skills, such as Breath of Life and Rite of Passage (listed below) they have the same wording of "healing allies" and yet they also apply to the caster rather than excluding like Soul Siphon does.
Developers please consider changing Soul Siphon to allow it to heal the caster, this would add a refreshing pace to healing for the NB healers out there. It would also allow Soul Siphon to be a desirable ultimate for all builds, rather than just an inferior morph. I'm certain of one thing though, something has to be changed because currently this ultimate tool-tip is downright deceiving.
