Respecing Life Remnants ate Vitality support gem

1) getting the first ascendancy on blood mage feels like gimping myself for no reason
2) I wanted to take Vitality support gem out so I can slot it into another aura and not have to deal with life cost for skills
3) I unspeced Sanguimancy, losing Life Remnants aura
4) Vitality gem is gone

As there is not enough support gems as is, this SUCKS. I'm now a support short and have nothing to show for it. Respecing back into Sanguimancy didn't bring it back, it's just back to sucking and I don't have enough gold to unspec it again.

Same issue is happening to me. Unspecced Sanguimancy just to be able to clear Trials of Chaos easier. Now I've added the point again my Vitality and Clarity supports are missing.

It really feels like I've made all the wrong choices into trying this. Feels bad already to pick Blood Mage. Feels worse now that my gems are deleted.
